Loom Knit Patchwork Baby Blanket Pattern: Beginner Afghan Throw (PDF Download)
If you’ve been wanting to learn loom knitting but weren’t sure where to start, a patchwork baby blanket is honestly one of the most rewarding projects you can pick up. It’s forgiving for beginners, customizable to any color palette, and the finished product is something you’ll genuinely be proud to gift — or keep. This pattern walks you through everything you need to know to create a beautiful, cozy patchwork baby afghan on a round or rectangular loom, no prior knitting experience required.
Why Loom Knitting Is Perfect for Baby Blankets
Traditional needle knitting has a learning curve that can feel steep. Loom knitting removes a lot of that friction. Instead of balancing two needles while trying to manage tension, you work on a stationary frame with pegs, and your hands focus on one simple tool — a loom hook — to move yarn through loops. For a baby blanket, this matters because even tension produces a fabric that’s soft and consistent, which is exactly what you want wrapped around a newborn.
Patchwork-style loom knitting takes this even further. Rather than knitting one enormous swatch of fabric, you knit individual squares or rectangles and then sew or join them together at the end. This means you can work in short sessions — finish a square while watching TV, tuck another one in while waiting at an appointment — and slowly build up to a full blanket without ever feeling overwhelmed.
The finished blanket in this pattern measures approximately 36 x 36 inches, which is a standard baby blanket size suitable for crib, stroller, and tummy time use. You can also adjust the number of squares to create a larger throw-size afghan by adding more rows of patches.
Materials You’ll Need
Before casting on, gather the following supplies. Most of them are available at any craft store or online retailer.
Yarn: Choose a bulky or super bulky weight yarn (size 5 or 6) labeled as machine washable. For a baby blanket, look for yarns specifically designated as baby-safe — free from scratchy fibers and easy to care for. Some popular options include Lion Brand Pound of Love, Bernat Baby Blanket yarn, or Red Heart Soft yarn. You’ll need approximately 800–1,000 yards depending on your chosen square size and the total number of patches.
Loom: A small rectangular or square loom with 24–36 pegs works well for knitting individual squares. A rake loom or a dedicated small square loom are both excellent. If you have a knitting board, that works too. For this pattern, each square is knitted flat, so you don’t need a closed round loom.
Loom Hook: Included with most looms, but pick up an extra if yours has gone missing. A metal hook tends to be more durable than plastic.
Tapestry Needle: You’ll use this for seaming the squares together and weaving in your yarn ends.
Scissors
Stitch Markers (optional): Helpful for keeping count on wider looms.
Yarn in Multiple Colors: The patchwork look comes from varying your color from square to square. A classic baby palette might include soft yellow, mint green, blush pink, and white. For a more modern or gender-neutral approach, try shades of gray, cream, and dusty blue. You can use as many or as few colors as you like.
Understanding the Stitch
This pattern uses the flat knit stitch (also called the U-wrap or E-wrap stitch, depending on your loom type), which produces a classic stockinette texture. If you’re completely new to loom knitting, take ten or fifteen minutes to practice on a separate piece of yarn before starting your first square. You’ll find that after just a few rows, the motion becomes second nature.
The flat knit stitch works as follows: wrap your yarn around each peg from left to right (or right to left, just stay consistent), then use your loom hook to lift the bottom loop on each peg up and over the top loop, letting it drop to the inside of the loom. Repeat this process across all pegs for each row. It sounds more complex in words than it is in practice — once you see it, you’ll understand it immediately.
For added texture and interest across different squares, you can also introduce a simple purl stitch or an alternating seed stitch pattern on some patches. Instructions for those variations are included later in this post.
The Pattern: Step-by-Step Instructions
Finished Dimensions
Each square: approximately 6 x 6 inches
Total squares needed: 36 (arranged in a 6 x 6 grid)
Finished blanket size: approximately 36 x 36 inches
You can increase this to a 7 x 7 or 8 x 8 grid of squares for a larger baby throw or lap blanket.
Casting On
Set up your loom for flat panel knitting. For 6-inch squares in bulky weight yarn, you’ll typically use 12–14 pegs. Cast on using the e-wrap cast on method: anchor your yarn on the first peg, then wrap each peg from left to right in a single clockwise loop. Once all pegs are wrapped, wrap back across from right to left, then begin knitting off.
Alternatively, use a chain cast on for a neater edge: create a slip knot, place it on your first peg, then use your hook to chain from peg to peg across the row. This gives your square a tighter, more defined cast on edge, which makes seaming easier later.
Knitting the Square
Row 1: Working from left to right, e-wrap each peg. Knit off by lifting the bottom loop over the top loop on each peg.
Row 2: Working from right to left, e-wrap each peg. Knit off.
Continue this back-and-forth flat knitting until your square measures 6 inches from cast on edge to current row. Depending on your yarn weight and loom gauge, this will typically be between 16 and 22 rows.
Tip: Measure your work frequently. Loom knitting gauge can vary between knitters and yarn brands. If your first square turns out to be 5.5 inches rather than 6 inches, simply adjust your row count on all subsequent squares to match — consistency across all 36 patches is what matters most.
Binding Off
Once your square reaches 6 inches, it’s time to bind off. The basic bind off for flat loom knitting goes like this: knit the first two pegs as normal. Then use your hook to pull the loop from peg 1 over peg 2, leaving only the new loop on peg 2. Knit peg 3, then pull the loop from peg 2 over peg 3. Continue across the row until one loop remains. Cut your yarn, leaving a 6-inch tail, and pull the tail through the final loop to secure it.
This gives you a stretchy, clean bound off edge that will lie flat when seamed.
Making All 36 Squares
Repeat the cast on, knitting, and bind off steps 36 times. Organize your color choices before you begin so you have a plan for your color layout. A simple approach is to assign six colors and make six squares in each color, then arrange them in a repeating diagonal or checkerboard pattern. If you prefer a more spontaneous look, assign colors randomly as you go.
Some knitters find it helpful to work on multiple squares at the same time — cast on three or four squares using the same yarn, work them simultaneously, and rotate through them session by session to keep things interesting.
Texture Variations for Different Squares
Once you’re comfortable with the flat knit stitch, try these variations to add visual interest:
Seed Stitch Square: Alternate between a knit stitch and a purl stitch on each peg across the row. On the following row, purl where you knitted and knit where you purled. This creates a bumpy, textured fabric that lies flat and adds great tactile interest to the blanket.
Ridged Garter Square: Alternate between knit rows and purl rows every two rows. The result mimics the look of garter stitch in traditional needle knitting and creates a lovely horizontal ridged texture.
Twisted Stitch Square: Instead of a standard e-wrap, twist your yarn in the opposite direction when wrapping the pegs. This creates a slightly tighter stitch with a cabled appearance. It takes a little more tension management, but the result is striking.
Using two or three of these variations alongside the plain stockinette squares will give your finished blanket depth and visual complexity without requiring advanced techniques.
Adding a Border to Each Square (Optional)
If you’d like crisp, clean edges on your squares before seaming, you can crochet or loom-knit a single border around each finished patch. Using a crochet hook and your border color yarn, join your yarn at any corner, then single crochet evenly around all four edges of the square, placing three single crochets in each corner to keep the edges from curling. Fasten off and weave in ends.
This step takes extra time but produces a very professional-looking final result and also helps if any of your squares came out slightly different sizes — the border gives you a bit of room to adjust and even things out.
Seaming the Squares Together
Once all 36 squares are complete, it’s time to assemble your blanket. Lay all your squares out on a flat surface — the floor works great for this — and arrange them in your chosen color pattern. Take a photo of your arrangement before you start seaming so you can reference it as you work.
There are two common methods for joining squares: mattress stitch seaming and single crochet joining.
Mattress Stitch Seaming: Thread your tapestry needle with a length of matching or contrasting yarn. Hold two squares with right sides facing up, edges touching. Working from the bottom of the seam to the top, insert your needle under the first bar between the first and second stitches on one square, then under the corresponding bar on the other square. Pull the yarn through gently to bring the two edges together. Continue alternating between the two squares until the seam is complete. This creates a nearly invisible seam when done in matching yarn.
Single Crochet Joining: Hold two squares with wrong sides together. Using a crochet hook and your yarn, insert the hook through both layers at the corner, chain one, then single crochet evenly across the edge, inserting through both layers with each stitch. This creates a small ridge on the right side of the blanket, which can actually add to the patchwork aesthetic if you use a contrasting yarn color.
Work in rows first: seam all squares in each horizontal row together, then seam the rows to each other. This organized approach keeps the blanket square and prevents the finished project from skewing.
Adding a Border to the Finished Blanket
A border unifies all the squares and gives your blanket a polished, finished look. Once all squares are seamed together, pick up stitches around the entire outside edge using a loom or a crochet hook.
For a simple crocheted border, join your yarn at any corner, single crochet evenly around the entire blanket, and place three single crochets at each outer corner. Work 2–3 rounds of single crochet, then fasten off. For something more decorative, finish the outer round with a shell stitch or a simple scallop.
For a loom-knitted border, you can use a long rake loom or a flexible loom to pick up stitches along each edge and work 4–6 rows of flat knit stitch, then bind off and seam the corners.
Care Instructions for Your Baby Blanket
Always defer to the yarn label for care instructions, but most machine-washable baby yarns can be washed in cold or warm water on a gentle cycle. Lay the finished blanket flat to dry to prevent stretching. Avoid fabric softener, which can break down the yarn fibers over time.
If you’re gifting the blanket, include the yarn label or a small care card so the recipient knows how to maintain it.
Tips for Beginners
Keep your tension even and relaxed. One of the most common beginner issues in loom knitting is wrapping the yarn too tightly, which makes the stitches difficult to lift off the pegs and can cause the fabric to bunch. If you find yourself struggling to knit off, loosen your wraps slightly.
Use stitch markers at the beginning and end of each row so you never lose your place. This is especially helpful when you’re learning a new stitch variation.
Don’t skip weaving in your ends. Every square will have at least two tails — one from casting on and one from binding off — and skipping this step means loose ends will work their way out through the fabric over time. Use your tapestry needle to weave each tail in at least 2–3 inches before trimming.
Work in good lighting. Loom knitting is easier when you can clearly see the loops on your pegs, especially when working with dark or variegated yarns.
Making This Pattern Your Own
One of the great joys of a patchwork design is how infinitely customizable it is. Here are a few ways to personalize your blanket:
You can use a single color throughout for a monochromatic look that feels modern and sophisticated. You can incorporate stripes within individual squares by changing yarn colors every two rows. You can spell out a baby’s initial or name using duplicate stitch embroidery added after the squares are knitted. You can scale the squares down to 4 inches and increase your total count to 81 squares (9 x 9) for a more intricate look with the same finished blanket size.
