Rainbow Striped Scrap Yarn Blanket for Beginners – Free Crochet Pattern
There is something deeply satisfying about turning a pile of leftover yarn into something beautiful. If you have been crocheting for a while, you probably have a stash of odds and ends sitting in a bag somewhere — half a skein of coral, a few yards of dusty blue, some sunshine yellow you bought on impulse. This pattern is made for exactly that yarn. The Rainbow Striped Scrap Yarn Blanket is beginner-friendly, endlessly customizable, and one of those projects you will want to make again and again because no two ever look exactly alike.
Whether you are a brand new crocheter working on your very first blanket or someone who has been in the craft for years and just wants a mindless, satisfying project to work on while watching television, this pattern has you covered. Let’s dive in.
Why This Blanket Pattern Is Perfect for Beginners
The biggest challenge beginners face with blanket patterns is complexity. Many intermediate and advanced patterns ask you to work in rounds, track multiple stitch counts simultaneously, or follow a chart. This pattern does none of that. Every row is worked flat, back and forth, using just a few simple stitches you can learn in an afternoon.
The stripe format is also enormously forgiving. Because the color changes every few rows, any slight inconsistency in your tension or stitch count is almost invisible. The eye is drawn to the riot of color rather than to individual stitches. This makes the Rainbow Striped Scrap Yarn Blanket one of the best crochet projects for building confidence.
Beyond technique, the scrap yarn format means there is no pressure to buy a specific product. You use what you have. You can swap colors freely, adjust the width of your stripes, and make every decision based on your personal taste and your stash. That kind of creative freedom is rare in a beginner pattern, and it makes the finished object feel truly yours.
Materials You Will Need
Because this is a scrap yarn pattern, the materials list is intentionally flexible. Here is what you need as a general guide.
Yarn: Any worsted weight (size 4) yarn in as many colors as you like. You can use as little as 10 yards of any given color for a thin stripe, or several hundred yards if you want a wide section. Acrylic yarn works beautifully here because it is affordable, widely available, and easy to care for. Cotton or wool work too, but try to keep all your yarns at a similar weight so your tension stays consistent from stripe to stripe.
Hook: A size 5.0 mm (US size H-8) crochet hook is a great starting point for worsted weight yarn. If your stitches feel tight, go up a hook size. If they feel loose and loopy, go down a size.
Scissors: Any pair will do.
Yarn needle: You will need this for weaving in your ends. Since this is a striped pattern, you will have a lot of them, so keep your needle handy throughout the project.
Measuring tape: Optional, but helpful if you want your blanket to reach a specific size.
Yarn Color Planning
One of the most enjoyable parts of making this blanket is planning your color order. Since you are working with scrap yarn, you likely have a variety of shades already. Here are a few ways to think about your color arrangement.
True rainbow order: Arrange your yarns in the classic ROYGBIV sequence — red, orange, yellow, green, blue, indigo, violet — and repeat the sequence as many times as needed until your blanket reaches the desired length. This creates the most visually cohesive result and looks stunning on a bed or couch.
Random scrappy order: Pull colors out of your stash as you go and change whenever you run out or feel like switching. This approach is completely spontaneous and results in a truly one-of-a-kind piece.
Gradient or ombre approach: If you happen to have multiple shades of the same color family, arrange them from lightest to darkest within each color family. For example, work through pale pink, medium rose, deep burgundy, then transition into light peach and warm orange. This creates a softer, more sophisticated look while still using scrap yarn.
Two-color stripes: If your stash leans heavily toward one or two colors, consider a simple alternating stripe pattern in just two or three complementary shades. This is a clean, modern look that works especially well for baby blankets.
There is no wrong choice. The beauty of scrap yarn blankets is that they celebrate variety.
Gauge
Gauge matters most when you need a garment or item to fit specific measurements. For a blanket, gauge is less critical — your finished size may vary a little from the measurements listed here, and that is perfectly fine. As a general reference, with worsted weight yarn and a 5.0 mm hook, you can expect approximately 14 double crochet stitches and 8 rows to equal about 4 inches.
If you want a specific finished size, work a small gauge swatch first and adjust your starting chain accordingly.
Abbreviations and Stitch Guide
This pattern uses American crochet terminology.
ch – chain
sl st – slip stitch
sc – single crochet
dc – double crochet
sk – skip
st – stitch
rep – repeat
RS – right side
WS – wrong side
If you are new to crochet, the only two stitches you truly need for this blanket are the chain and the double crochet. The double crochet is taller than a single crochet, which means your blanket will grow more quickly in length with every row. It also creates a fabric with a lovely drape and a slight openness that gives the finished blanket a cozy, airy feel.
Pattern Instructions
Finished Size
The instructions below will produce a blanket approximately 40 inches wide by 50 inches long, which is a great size for a lap blanket, a toddler blanket, or a couch throw. To make it wider, add more chains to your starting foundation in multiples of three. To make it narrower, subtract chains in multiples of three. To make it longer, simply keep adding rows until you reach your desired length.
Foundation Chain
With your first color of yarn, make a foundation chain of 129 chains (or any multiple of 3, plus 3 for your turning chain).
To check your chain length before you start crocheting, lay it flat and measure it. It should measure approximately 40 inches. Adjust up or down as needed.
Row 1 (Right Side)
Starting in the 4th chain from your hook (the first 3 chains count as your first double crochet), work 1 dc in each chain across. At the end of the row, you should have 127 dc total (including the turning chain).
Turn your work.
Row 2 (Wrong Side)
Ch 3 (counts as first dc). Work 1 dc in each st across, working into the top two loops of each stitch. When you reach the end, work your final dc into the top of the turning chain from the previous row.
Turn your work.
Continue Working Rows
Continue working rows of double crochet, turning at the end of each row and chaining 3 at the beginning of every row. This is the main body of the blanket, and every row is exactly the same.
Changing Colors
Change your color whenever you like. For a classic rainbow stripe effect, change every 4 rows. For thinner stripes, change every 2 rows. For wider stripes, change every 6 to 8 rows.
To change colors, work the last double crochet of a row until you have two loops remaining on your hook. Then drop your current yarn, pick up your new color, and pull it through those two loops to complete the stitch. Chain 3 with your new color and turn your work. You have successfully changed colors.
Leave tails of about 6 inches when you join or cut yarn. You will weave these in at the end.
Continuing the Blanket
Keep working rows and changing colors until your blanket measures approximately 50 inches from top to bottom, or until you are happy with the length. The exact number of rows will depend on your gauge and how often you switch colors.
Finishing Round
Once you have reached your desired length, work one final round of single crochet all the way around the entire blanket, including the sides. This creates a tidy, even border and gives the blanket a more polished look.
To work the border, do not turn your work at the end of your final row. Instead, rotate the blanket 90 degrees and work single crochet stitches evenly down the side edge, placing one sc into the side of each dc row as you go. When you reach the corner, work 3 sc into the corner stitch to turn the corner cleanly. Continue across the bottom (working into each foundation chain), work 3 sc in the corner, work up the other side, 3 sc in the final corner, and join with a slip stitch to your first sc.
Fasten off and weave in your ends.
Weaving in Ends
This is the least glamorous part of any striped project, but it is essential. Thread your yarn needle with one tail at a time and weave it through the backs of several nearby stitches in a zigzag pattern. Trim the excess close to the fabric. Repeat for every tail until all ends are secure.
To make this step less overwhelming, weave in your ends as you go rather than saving them all for the end. After every color change, take a few minutes to secure those tails before moving on. Your future self will thank you.
Tips for a Beautiful Finished Blanket
Keep your tension consistent. Your tension is the amount of tightness you apply to the yarn as you crochet. If your stitches are very different from row to row, your blanket may have a wavy or uneven look along the edges. Try to hold your yarn and hook the same way throughout the project. If you notice your tension changing when you switch yarn brands or fiber types, adjust your hook size to compensate.
Block your blanket. Blocking is the process of wetting or steaming your finished piece and shaping it while it dries. For acrylic yarn, you can wet block by soaking the blanket in cool water, gently squeezing out the excess moisture (never wring), and laying it flat to dry in the shape you want. For wool, use a steamer or a damp pressing cloth and an iron. Blocking relaxes the stitches, evens out any inconsistencies in tension, and gives your finished piece a much more professional appearance.
Use a consistent yarn weight. If possible, stick to yarns of the same weight throughout the project. Mixing a worsted weight yarn with a bulky yarn will create a noticeable bump or ridge at that color change and will affect the drape of the entire blanket. If your stash is a mix of weights, try to group similar weights together rather than scattering them randomly.
Label your yarn. If you are working with unmarked leftovers, it can be hard to remember what type of yarn a particular scrap is. Before you start, wind your scraps into small balls and tuck a small tag inside each one noting the fiber content. This will help you with washing instructions later.
Count your stitches at the end of each row. This takes only a few seconds and can save you a lot of frustration. If your stitch count drifts — a common beginner issue caused by accidentally crocheting into the turning chain or skipping the last stitch — catch it early and fix it before the error multiplies across several rows.
How to Make This Blanket Larger or Smaller
The beauty of a stripe blanket worked flat is how easy it is to resize.
For a baby blanket, start with a chain of about 75 to 90 stitches and work until the blanket measures around 30 to 36 inches long. A baby blanket uses far less yarn, making it an ideal stash-buster for those really tiny scraps.
For a full-size throw or afghan, start with a chain of around 180 stitches and work until the blanket measures 60 to 65 inches long. This will be a more significant time commitment but is a truly impressive finished piece.
For a bed runner or table runner, narrow the width to around 50 to 60 stitches and work as long as you need. A runner in rainbow stripes makes a striking accent piece for a dining table or the foot of a bed.
Gift Ideas for This Blanket
The Rainbow Striped Scrap Yarn Blanket makes a wonderful handmade gift. Because you are working with scraps, you can tailor the color palette to the recipient’s taste. Love neutrals? Use oatmeal, ivory, grey, and cream for a sophisticated monochromatic stripe. Making a baby gift? Soft pastels — pale mint, blush pink, lavender, and buttery yellow — are universally beloved. Making something for a sports fan? Work their team colors in alternating stripes.
A handmade blanket communicates care and effort in a way that a purchased gift rarely does. When people learn that you crocheted it from yarn you already had at home, the impact is even greater.
Caring for Your Finished Blanket
Always check the care labels of the individual yarns you used before washing your finished blanket. When in doubt, hand wash in cool water with a gentle detergent and lay flat to dry. Avoid wringing or twisting the blanket, which can distort the stitches. If all of your yarn is machine-washable acrylic, you can machine wash on a gentle cycle in cool water and tumble dry on low.
Share Your Make
If you make this blanket, please share a photo. Whether you post it to Instagram, Pinterest, Facebook, or a crochet community like Ravelry, seeing how other makers interpret a pattern — the colors they choose, the sizes they make, the little variations they add — is one of the most joyful parts of being part of the crochet community. Tag your post so others can find it and be inspired.
This Rainbow Striped Scrap Yarn Blanket is a pattern worth making more than once. The first one might go to a friend. The second might live on your couch. The third might be a wedding gift for someone who loves color. However you use it, you are not just crocheting a blanket. You are turning yarn that might have been forgotten into something warm, useful, and full of life.
Happy crocheting.
