About this pattern

A DK-weight baby jumper worked in two flat 33-row-ribbed torso panels (33 HDC wide) with 7 rows of micro bobble stitch each, plus two sleeves worked directly into each armhole starting at 28 HDC around. Ribbing uses a 3mm hook; the torso, sleeves, and their ribbing use a 4mm and 3mm hook respectively. Assembly is limited to side seams, shoulder seams, and picked-up neckline ribbing — no sleeve setting-in required.

The pattern

Written out round by round

Materials

  • Double Knit (DK) weight yarn
  • 4mm crochet hook (main body)
  • 3mm crochet hook (ribbing)

Abbreviations

  • HDC = half double crochet
  • SC = single crochet
  • BLO = back loop only
  • MBS = micro bobble stitch
  • SS Dec = slip stitch decrease

Ribbing

Repeat Row 2 for a total of 33 rows of ribbing.

Do not fasten off if continuing with the same color.

Row 1Using the 3mm hook, chain 7; work 1 single crochet (SC) in the second chain from hook and across.
Row 2Chain 1, turn; work 1 SC in the back loop only (BLO) across.

Torso Panels

Make 2

Repeat the sequence of 3 rows of HDC followed by 1 row of MBS until there are 7 rows of bobbles.

End with 3 final rows of HDC.

Make 2 identical panels for front and back.

Row 1Switch to the 4mm hook; chain 2, turn, and work 1 HDC into the side of each ribbing row. (33 HDC)
Rows 2–3Chain 2, turn, and work 1 HDC into each stitch across for 2 more rows.
Row 4Chain 1, turn, and alternate 1 single crochet (SC) and 1 micro bobble stitch (MBS) across.

Sleeves

Make 2

Repeat the four-round pattern (3 rounds HDC, 1 round MBS) four times for 16 rounds total.

Finish with 2 rounds of HDC.

Round 1Attach yarn at the bottom of the armhole using a 4mm hook; chain 2, work HDC evenly around (about 28 HDC), and join with a slip stitch. (28 HDC)
Rounds 2–3Chain 2, turn, and work 1 HDC in each stitch for 2 more rounds.
Round 4Chain 1, turn, and alternate micro bobble stitch (MBS) and SC around.

Sleeve Ribbing

Make 2

When complete, slip stitch the ribbing edges together.

Round 1Switch to a 3mm hook; chain 4, work 3 SC starting from the second chain; slip stitch into the next two stitches of the sleeve edge; chain 1, turn, and work 3 SC in the back loop only; repeat this pattern around the sleeve.

Neckline Ribbing

Close the neckline ribbing with slip stitches or sewing.

Round 1Using the 3mm hook, attach yarn at the center back; chain 4, work 3 SC starting in the second chain from the hook; slip stitch into the next unworked stitch, then slip stitch decrease (SS Dec) across the next two stitches; continue regular ribbing around the neckline with decreases at the shoulders for a neat fit.

Assembly

Step 1Place both panels together with right sides facing out.
Step 2Mark 10 rows down for armholes on both sides.
Step 3From each side edge, count in 10 stitches and mark the 11th to form the neckline, leaving 13 stitches open.
Step 4Sew the side seams from bottom up to the armhole markers.
Step 5Sew shoulder seams from edges to neckline markers.
Step 6Weave in all loose ends securely.
Step 7Block lightly if desired to shape.

Tester's notes

If changing color between the ribbing and torso panel, join the new color on the last ribbing row instead of fastening off, per the pattern note.

the neckline, count 10 stitches in from each side edge and mark the 11th — the 13 stitches left between markers form the opening, and a one-stitch error shifts it off-center.

Each panel needs 7 rows of MBS total; keep tension even across HDC and bobble rows so the panel doesn't taper narrower where the bobbles sit.

Gauge Swatch: Chain 17 and work 15 half double crochets (HDC); continue for 6 rows total of HDC; finished swatch should measure about 3.25 inches wide by 2 inches tall; adjust hook size to match the gauge if necessary.

This pattern is easy to customize by color: pick your favorite yarn color combinations for the ribbing, torso panels, and sleeves to give the finished sweater a unique handmade look, whether for everyday wear or gifting.

Gauge check

After the first 6 rows of the gauge swatch (chain 17, 15 HDC), measure across for 3.25 inches and down for 2 inches.

If the swatch runs smaller than that, move up a hook size; if larger, drop down a size, and recheck before starting the 33-row ribbing.

Stitch-count checkpoints

  • Sleeves · Round 1: 28 sts

If something looks wrong

The torso panel flares or puckers where
The 33-HDC pickup along the ribbing edge was uneven or off-count. Recount to exactly 33 HDC across before working torso rows 2-3.
The sleeve doesn't sit evenly once joined at the armhole.
Round 1 of the sleeve didn't land on 28 HDC, or one of the 16 patterned rounds plus 2 finishing rounds was skipped. Recount stitches and rounds before seaming.
The neckline sits crooked or noticeably wider on one side.
The 10-stitch offset from the side edge was measured differently on each side, shifting the 13 open stitches out of center. Remeasure both sides from the edge and remark before assembly.
One panel's bobble texture looks flatter than the other.
MBS tension varied between panels or a bobble row was missed — each panel needs 7 rows of bobbles. Count bobble rows against the finished panel before joining side seams.

Yarn substitutions

Acrylic, DK weightClosest match to the pattern's gauge swatch (3.25 x 2 inches over 15 HDC, 6 rows); no hook change needed and easiest to hit exact stitch counts.
Cotton, DK weightLess stretch through the 33-row ribbing; going up to a 3.5mm hook for ribbing keeps it from binding, though drape on the torso panels stays firmer.
Wool-blend, DK weightMore give and lighter fabric overall, but wool typically works up looser — recheck the gauge swatch and consider dropping to a 3.75mm hook if the 15-HDC swatch runs oversize.
FAQs

Questions

Is any part of this jumper actually sewn?

Yes, but only at two seams: the side seams up to the armhole marker and the shoulder seams to the neckline marker. There's no sewing in of sleeves or piece-by-piece assembly beyond those two seam lines.

How is the neckline shaped without separate decreases?

It's marked, not shaped with stitches: count 10 stitches in from each side edge, mark the 11th, and leave the 13 stitches between the two markers open. Shoulder seams are then sewn from the outer edges in to those markers.
