Free Simply Soft Afghan Knit Pattern: A Cozy Heirloom You Can Make This Weekend

There is something deeply satisfying about wrapping yourself in a blanket you made with your own hands. The weight of it, the softness against your skin, the way it drapes across the couch like it was always meant to be there — these are the quiet rewards of knitting. And if you have been searching for a pattern that delivers all of that warmth without burying you in complicated instructions, you have landed in exactly the right place.

This free Simply Soft afghan knit pattern is designed for knitters who want a finished product that looks polished and professional without spending weeks wrestling with complex cable charts or obscure stitch combinations. Whether you are a confident beginner ready to push past dishcloths and scarves, or an intermediate knitter looking for a satisfying weekend project, this pattern will guide you from cast-on to bound-off edge with clear, approachable steps.

The star of this project is Caron Simply Soft yarn, one of the most beloved yarns in the craft community. If you have never worked with it before, you are in for a treat. Let’s start from the beginning and walk through everything you need to know.

Why Caron Simply Soft Is the Perfect Yarn for an Afghan

Before we get into the pattern itself, it is worth spending a moment on why this particular yarn earns such enthusiastic praise from knitters and crocheters alike.

Caron Simply Soft is a worsted weight, 100% acrylic yarn that manages to feel remarkably soft against the skin — far softer than many acrylics on the market. It has a gentle drape that gives finished afghans a fluid, elegant look rather than the stiff, boxy appearance that lower-quality acrylics sometimes produce. It is also machine washable and machine dryable, which makes it an excellent choice for afghans that will actually be used. A blanket that has to be hand-washed and laid flat to dry is a blanket that rarely gets the love it deserves.

The color range available in Simply Soft is another major selling point. From deep, moody jewel tones to soft pastels to rich neutrals, the palette is broad enough to satisfy nearly any aesthetic. You can create a sophisticated charcoal blanket for a living room, a soft lavender throw for a nursery, or a vibrant striped afghan that uses up multiple colors you already have in your stash.

Simply Soft comes in standard skeins of approximately 315 yards each, which means you can easily calculate how many skeins you need for a project of any size. For the afghan in this pattern, we will be working with a generous lap blanket size, and the yardage requirements are clearly spelled out below.

Materials You Will Need

Getting your materials organized before you begin saves time and frustration once you are mid-project. Here is everything you will need to complete this simply soft afghan.

For yarn, gather approximately 1,800 to 2,000 yards of Caron Simply Soft in your chosen color. That works out to about six skeins for a solid color blanket, or you can divide that across two or three colors if you prefer stripes or color blocking. The finished blanket will measure approximately 40 inches wide by 50 inches long, which is a comfortable lap and couch throw size. If you want a larger blanket — something that covers a full bed or generously wraps an adult — plan to add at least two additional skeins and adjust your cast-on number accordingly using the notes included later in this pattern.

For needles, you will want a US size 8 (5.0mm) circular needle at least 32 inches long. Circular needles are not required for knitting flat, but they are strongly recommended for afghans because the cable holds the weight of your growing work without straining your wrists. You will be knitting back and forth in rows rather than joining in the round, so circular needles used flat function exactly like straight needles — just more comfortable for heavy projects.

You will also need a yarn needle for weaving in ends, a tape measure, and scissors. Stitch markers are optional but helpful if you are adding any pattern variation with borders.

Understanding the Stitch Pattern

This afghan uses a combination of knit and purl stitches arranged in a simple seed stitch border surrounding a central panel worked in a textured moss stitch variation. Both of these stitches are made using only the two most basic knitting techniques — the knit stitch and the purl stitch — which means this pattern is genuinely accessible to anyone who has mastered those fundamentals.

Seed stitch is created by alternating knit and purl stitches across a row, then on the following row, purling the knit stitches and knitting the purl stitches. The result is a dense, flat fabric with a beautifully pebbly texture that lies flat without curling at the edges. This makes it ideal for afghan borders, where you want the edges to stay neat and even.

The central moss stitch panel follows a similar principle but with a two-row repeat that creates slightly more elongated texture than traditional seed stitch. When worked in Simply Soft yarn, this stitch catches light in a way that makes the finished blanket look far more intricate than it actually is. Guests will ask how you made it. The answer, delightfully, is that it was not very hard at all.

Gauge

Before casting on the full blanket, knit a gauge swatch. This step is easy to skip and frequently regretted. Gauge determines whether your finished blanket will be the size you expect it to be.

Using your US size 8 needles and Simply Soft yarn, cast on 20 stitches and work in the stitch pattern described below for approximately 4 inches. Bind off and measure your swatch. You are looking for 18 stitches and 24 rows to equal 4 inches in the moss stitch pattern.

If your stitches are too large and your swatch is bigger than 4 inches across, try a smaller needle. If your stitches are too small and your swatch is tighter than expected, move up a needle size. These small adjustments make a significant difference in the final dimensions of your blanket.

The Free Simply Soft Afghan Knit Pattern

Now, the part you have been waiting for. Read through the entire pattern once before casting on so that nothing catches you off guard mid-project.

Finished Size: Approximately 40 inches wide by 50 inches long

Yarn: Caron Simply Soft, worsted weight, approximately 1,800 to 2,000 yards

Needles: US size 8 (5.0mm) circular needle, 32 inches or longer

Gauge: 18 stitches and 24 rows = 4 inches in moss stitch

Abbreviations:
K means knit. P means purl. CO means cast on. BO means bind off. RS means right side. WS means wrong side. Rep means repeat. St or sts means stitch or stitches.

Cast On

Using the long-tail cast on method, cast on 181 stitches. The long-tail cast on creates a sturdy, stretchy edge that is well-suited for blankets.

Border Setup (Rows 1 through 6)

These first six rows establish the seed stitch border along the top and bottom edges of the blanket. Working the same border pattern at the beginning will create a matching edge when you return to it at the end.

Row 1 (RS): K1, P1, rep from to last stitch, K1.
Row 2 (WS): K1, P1, rep from to last stitch, K1.
Row 3: Repeat Row 1.
Row 4: Repeat Row 2.
Row 5: Repeat Row 1.
Row 6: Repeat Row 2.

After six rows, your bottom border is complete and you should have a neat, flat band of seed stitch running across the cast-on edge.

Body of the Afghan

The body is worked using a combination of a 5-stitch seed stitch side border on each side with the moss stitch panel filling the center.

Set-Up Row (RS): K1, P1, K1, P1, K1 (this is your 5-stitch left border), place marker if desired, then begin moss stitch panel across the next 171 stitches, place marker if desired, then K1, P1, K1, P1, K1 (this is your 5-stitch right border).

Moss Stitch Panel (worked over 171 center stitches)

Rows 1 and 2 (beginning RS): K1, P1, rep from to last stitch of panel, K1.
Rows 3 and 4: P1, K1, rep from to last stitch of panel, P1.

These four rows create the moss stitch repeat. Continue repeating these four rows, keeping the 5-stitch seed stitch borders consistent on each side throughout the body, until your work measures approximately 48 inches from the cast-on edge, ending after completing a Row 4 of the moss stitch pattern.

Helpful Notes on Maintaining the Borders

The 5-stitch seed stitch borders on each side are worked as follows on every row, regardless of where you are in the moss stitch repeat: K1, P1, K1, P1, K1 at the beginning of the row, and K1, P1, K1, P1, K1 at the end of the row. Because you are always working these edge stitches the same way, they will naturally produce the seed stitch texture. If your count ever feels off, count your stitches — you should always have 181.

Closing Border

Once the body reaches 48 inches, work six more rows of seed stitch across all 181 stitches, exactly as you did for the opening border.

Row 1: K1, P1, rep from to last stitch, K1.
Row 2: K1, P1, rep from to last stitch, K1.
Repeat these two rows two more times for a total of six rows.

Bind Off

Bind off all 181 stitches in pattern on the next RS row, meaning knit the knit stitches and purl the purl stitches as you bind off. This keeps the bound-off edge consistent with the texture of the border and gives it a beautiful, finished appearance. Bind off loosely — use a needle one or two sizes larger for the bind-off row if you tend to bind off tightly.

Finishing Your Afghan

Cut the yarn, leaving a tail of at least 6 inches. Thread your yarn needle and weave in all ends securely, working the tails through at least 2 inches of fabric in different directions so they will not work loose over time and through washings.

Block your finished afghan for the best results. To block an acrylic yarn blanket, dampen it thoroughly with cool water, gently press out the excess moisture by rolling it in a clean towel, then lay it flat in its final dimensions and allow it to air dry completely. Blocking evens out your stitches, opens up the texture beautifully, and gives the finished blanket a professional, polished appearance that is noticeably better than an unblocked piece.

Customizing This Pattern

One of the great pleasures of a simple, well-structured pattern like this one is how easily it adapts to your personal preferences and the specific needs of your project.

To make a baby blanket, cast on 91 stitches and work until the piece measures 30 inches. You will need approximately three skeins of Simply Soft.

To make a full-size throw, cast on 241 stitches and work until the piece measures 60 inches. Plan on eight to ten skeins depending on your gauge.

For a striped version, change colors at the beginning of any row. When changing colors, carry the old color loosely up the side edge if you plan to return to it within four or five rows. If the color change is permanent, simply cut the old yarn and join the new color, leaving a 6-inch tail to weave in.

You can also experiment with the stitch pattern in the center panel. A simple stockinette center — knit on the right side, purl on the wrong side — gives a smooth, classic look that showcases variegated yarn beautifully. A garter stitch center — knit every row — produces a thick, squishy blanket that is incredibly warm. Both work beautifully with the seed stitch borders described in this pattern.

Tips for Knitting a Large Project Like an Afghan

Afghans are long-haul projects, even relatively simple ones. A few habits will make the process more enjoyable and help you produce a better finished piece.

Work on your blanket in consistent light. Texture stitches like moss and seed can be tricky to read in dim conditions, and mistakes are harder to spot until you have several more rows on top of them.

Count your stitches regularly, particularly during the first several inches when the pattern is still establishing itself. Catching a dropped stitch or an accidental yarn-over early saves significant frustration later.

Use a row counter or keep a simple tally in a notebook. When you set your knitting down and come back to it the next day, you will always know exactly where you are in the moss stitch repeat.

If you need to put the project down for an extended period, resist the temptation to leave it mid-row. Always finish the row you are working on before setting it aside. This keeps your tension consistent and makes it easier to pick the project back up.

Caring for Your Finished Afghan

One of the most practical advantages of Caron Simply Soft is its care instructions. Machine wash your finished afghan in cold or warm water on a gentle cycle. Tumble dry on low heat. The fiber holds up beautifully through repeated washing without pilling or losing its softness, which makes it genuinely well-suited for blankets that will be used and loved rather than stored.

Avoid high heat, which can cause acrylic fibers to melt slightly and lose their soft texture permanently. Keep the dryer on a low or medium-low setting and remove the blanket while it is still slightly damp to finish air drying if you prefer.

A Pattern Worth Returning To

The best knitting patterns are the ones you return to again and again — gifting them to friends, making them in new colors, adapting them for different sizes as occasions arise. This free simply soft afghan knit pattern is that kind of pattern. It is simple enough to work on while watching television or talking with friends, but interesting enough to keep your hands happy and engaged. The finished result has the kind of timeless, handmade quality that makes it a meaningful gift and a treasured addition to any home.

Whether you knit it for yourself, make it as a baby gift, or wrap it up for a holiday present, this blanket carries something that store-bought throws simply cannot replicate — the warmth of the time you put into it, and the care that went into every stitch.

Cast on, get comfortable, and enjoy the process. The blanket will be finished before you know it.
