Can I make the hat without the leaf cluster?

Yes, the hat still reads as a blueberry with just the moss stitch dome, French knots, and ruffle brim. The leaf cluster is a quick addition but not essential to the overall look.

Do I need two different hook sizes?

Yes, the pattern calls for a US G-6 for the main fabric and a US E-4 for the ruffle brim and ribbing. The smaller hook keeps those sections snug against the larger stitches around them.

What if my gauge doesn't match exactly?

Since this is a newborn-sized set, swatching first really does matter here. If your moss stitch or single crochet swatch comes up different from the 18 stitches and 20 rows over 4 inches given, adjust your hook size until it matches.

How do the suspender straps attach to the pants?

The straps are made separately and then attached in a crossed position at the back, fastening in front with the two wooden buttons. This gives the pants that classic overall-style closure.

Why block the pieces before adding French knots?

I actually suggest reviewing the French knots after blocking, since the wet blocking process can loosen embroidery slightly. Tightening them at the end keeps the seeds looking crisp in the finished photos.

About This Pattern

There's something about this set that feels like the first cool morning of fall, the kind where you want to wrap a baby in something a little whimsical. The navy dome and scattered white seeds do all the talking here. You don't need a loud color story when the shape itself is the punchline.

Picture this folded on a changing table shelf, hat nested into the waistband of the pants, waiting for its first wear. The wavy steel blue brim catches light differently than the flat navy body. It reads as handmade in the best way, the kind of thing a visitor picks up and asks where you found it.

Start the hat crown with a magic ring and increase steadily until the dome reaches its full width.
Transition from Yarn A to Yarn B, then swap hooks to crochet the wavy ruffle brim.
Make three small leaves separately and sew them in a fan shape to the center of the crown.
Work each pants leg flat, starting with a ribbed ankle cuff before moving into the leg tube.
Seam the two finished legs together and crochet a ribbed waistband to join them.
Crochet two suspender straps and attach them crossed at the back with wooden buttons in front.
Finish by stitching French knots across the hat dome, then block both pieces to set their shape.

Yarn suggestions

Paintbox Yarns Simply DK works beautifully for this project with excellent stitch definition. Lion Brand Pound of Love is another great option, especially if you want something super soft against newborn skin. For warmer climates, try Paintbox Yarns Cotton DK, but definitely swatch first since cotton has less stretch than acrylic.
Avoid fuzzy or loosely spun yarns here. They’ll hide that lovely moss stitch texture you’re working so hard to create.
