Silver Block Toddler Sunsuit Knit Free Pattern
Introduction
This Silver Block Toddler Sunsuit is a sweet, simple knit made for little ones aged 18–24 months, and it is gentle enough for a first-time garment knitter. The design is a straight tube worked from the hem up, so there is no waist shaping and no complicated armhole math to worry about. A silver eyelet band at the hem gives it a crisp mid-century colorblock look, while the ice blue body stays plain and calm. The finished sunsuit feels soft and breathable in sport weight cotton, with two narrow shoulder straps and a buttoned crotch facing that make dressing easy.

Gauge
24 sts and 32 rows = 4" (10 cm) in stockinette stitch. Knit a small swatch in the round or flat, then measure a 4" section in the middle to check that your stitch and row counts match before you begin.
Tips Before You Start
- Cotton has little stretch, so knit your swatch and trust it — if you are between gauges, go up a needle size rather than down.
- When you join the cast-on round, check that the edge is not twisted before you knit the first stitch; a twist here cannot be fixed later.
- Use a locking stitch marker to hold the beginning of the round, and move it up as you work so you never lose your place in the long plain section.
- Keep your yarn overs loose and even on the eyelet rounds so the holes stay open and round after blocking.

Assembly and Finishing
Fold the crotch facing to the inside along the turning ridge and sew the bound-off edge to the wrong side of the body, leaving openings for the buttons. Sew buttons onto the facing. Sew the straps to the front and back shoulders, positioning them 3" (7.5 cm) apart from center. Try the sunsuit on and adjust the strap length as needed, then sew buttons onto the front straps for closure. Weave in all ends neatly on the wrong side. Block lightly by misting with water and patting flat to dry, pressing the hem and crotch facings gently into place.
Pro Tips and Variations
- Swap the silver hem band for a soft mustard or sage to change the colorblock mood while keeping the same eyelet detail.
- Add a second eyelet round a few rounds above the hem for a layered lace look, or repeat the eyelet band at the top edge for a matching finish.
- For a longer wear season, knit the straps a little longer and add extra buttonholes so the sunsuit can grow with your toddler.
