Sunshine Yellow Baby Romper Set Free Crochet Pattern

I love a baby set that feels like pure sunshine, and this one always makes me smile! We will crochet bib-front overalls in cheerful yellow and white stripes, then finish the gift with a matching beanie topped with a fluffy pom-pom and a pair of tiny thumbless mittens.

The construction is such fun. We start with the flat bib, then pick up stitches around all four edges to build the romper body in joined rounds. A clever crotch bridge splits the body into two little legs, and the stripes carry right down to the ribbed ankle cuffs.

This is an intermediate set, so it helps if you are comfortable working in the round, changing colours cleanly and following stitch counts. Take it section by section with me and you will be just fine. The finished romper fits newborn to 3 months.

• Invisible join: cut the yarn leaving a 6-inch tail, thread it on a yarn needle, insert the needle under both loops of the first stitch of the round from front to back, then back into the centre of the last stitch from front to back, and pull snug for a nearly seamless finish.
• Stripe colour change: work the last sc of the round until two loops remain on your hook, drop the current colour to the wrong side, pick up the new colour and pull it through both loops to complete the stitch. Carry a colour loosely up the inside when its next stripe is only a few rounds away.

Bib Front Pattern

The bib is worked flat in rows using Color A only. The body of the romper is worked in joined rounds, not spirals: slip stitch to the first sc, ch 1, then begin the next round in the first stitch. The ch 1 does not count as a stitch, and stitch counts appear at the end of every row and round.

Foundation: Ch 24.

Row 1 (RS): Sc in second ch from hook and in each ch across. Turn. (23 sc)

Row 2: Ch 1, sc in each st across. Turn. (23 sc)

Rows 3 to 18: Repeat Row 2 sixteen more times. (23 sc each row)

After Row 18 your bib should measure approximately 4.5 inches tall and 6.5 inches wide. Do not fasten off.

Romper Body Pattern

Now we work around the perimeter of the bib to create the body. This is the lovely moment where the flat piece turns into a tube!

Round 1: With RS of bib facing, work 18 sc evenly down the right side edge of the bib (approximately 1 sc per row, skipping every 3rd row edge to keep the fabric flat). Ch 28 to form the back of the romper. Work 18 sc evenly up the left side edge of the bib. Sl st to first sc to join. Ch 1. (64 sc total around the body: 18 + 28 ch + 18)

Finishing & Assembly

Weave in all yarn ends on the wrong side of the romper, paying special attention to the colour-change joins. Weave these at least 1 inch in two different directions so nothing can work loose.

Attach the wooden buttons using sewing thread and a needle, stitching through all layers securely, and always check the buttons before each wear to make sure they are still firmly attached.

For the hat, weave in all ends and make sure the pom-pom is knotted securely, because little hands love to tug. For the mittens, weave in all ends and check that each cuff seam lies flat and smooth.

Acrylic does not need blocking, but for extra-neat stitches you can soak each piece in cool water for 10 minutes, squeeze gently without wringing, roll in a clean towel, then pin to the finished measurements and leave to dry completely.

Tips

For 3 to 6 months, add 8 stitches to the bib foundation for 31 stitches instead of 23, add 4 stitches to the back chain for 32 instead of 28 to give a 76-stitch body, and add 4 rounds to each leg and 4 rounds to the hat dome before the crown shaping. Increase the brim ribbing to 60 rows.

For 6 to 9 months, add 12 stitches to the bib foundation for 35 stitches and add 6 stitches to the back chain for 34 instead of 28, then adjust the 86-stitch body to 84 stitches with a decrease round. Add 6 rounds to each leg and 6 rounds to the hat dome.

For a preemie size, simply switch to a 5.0 mm hook and keep the same stitch counts for a proportionally smaller set.

The whole set takes roughly 14 to 20 hours in total: the romper is the biggest piece at about 10 to 14 hours, and the hat and mittens together add another 4 to 6 hours. Machine wash cold on a gentle cycle in a mesh laundry bag and lay flat to dry.
