How to Make a Striped Baby Sweater (Size 18 Months – 2 Years)

Materials & tools you'll need

Step 1 — Work the front and back panels

Using your main body color yarn, begin with single crochet (sc) stitches and work until the panel reaches your preferred height for the lower body section. Switch to double crochet (dc) stitches and continue for a few inches to create the first stripe. Use a stitch marker to note where the next stripe begins, then switch to your second color yarn and work the same number of dc rows. Alternate between the two colors in this way until each panel reaches the desired total height. Work both the front and back panels identically, keeping careful track of your stripe sequence so they match up precisely when the sweater is assembled.

Step 2 — Crochet the sleeves

Using the main body color yarn, create a foundation chain slightly longer than half the width of the shoulder openings on your front and back panels — the extra length gives you room for seaming. Join the yarn in the first stitch and work in sc stitches until you reach the armhole point, approximately halfway along the sleeve length. Switch to dc stitches for a few inches, then move to the second color yarn and repeat the process to create the matching alternate stripe. When the sleeve reaches your desired length, bind off the stitches and weave in all ends. Make two sleeves in the same way.

Step 3 — Work the collar

Using the pink collar yarn and your tapestry needle, work a front post back double crochet (fpbpc) stitch into every stitch around the top edge of both the front and back panels. This alternating front post and back post technique creates a ribbed, decorative collar that sits neatly and securely around the neckline. Continue around the full neckline until the collar reaches your desired depth, then fasten off and weave in the ends.

Step 4 — Assemble the sweater

Thread your tapestry needle with brown yarn and sew the sleeves to the armholes of both the front and back panels, ensuring a seamless, even fit all the way around each armhole. Take your time with this step — it is the most important seam for the sweater's overall appearance and structure. Next, sew the shoulder seams together, then work down the side seams, continuing with brown yarn throughout. Be gentle and precise at every join for a professional, polished finish.

Step 5 — Final finishing

Once all seams are sewn, go over the entire sweater and check for any remaining loose ends. Weave in each one securely using your tapestry needle, working through several stitches in different directions to prevent anything from unraveling with wear or washing. Give the sweater a gentle press if needed and check that the stripes align correctly across the front, back, and sleeves. Your charming striped baby sweater is now complete and ready to wear!
