How to make a felt starfish hat for kids

Why a starfish headband works

I sewed custom starfish hats through several beach-party summers, so this shape was re-cut dozens of times before it earned a tutorial. A five-point star headband finishes three costumes at once — starfish, beach princess, and “the sea in general” (my kid’s real request, and the hardest brief of the year). It stays on without chin straps because an elastic headband flexes where a hat brim won’t.

Supplies

Make the star

Draw two concentric star shapes on freezer paper: outer star 7 inches across the points, inner star 4.5 inches. Trace the classic 5-point star outline freehand — slightly uneven points read more like a real starfish than a ruler-perfect star does. Iron freezer paper to the felt, cut along the outer line, peel, and you get a clean ring-shaped border piece. Repeat for a second layer.

Sew the two layers together

Blanket stitch the outer edge all the way around the ring, leaving a 2-inch gap. Stuff lightly — a single cotton ball’s worth per point is plenty — then close the gap. This thin stuffing makes the starfish hold points flat instead of folding in on the headband.

Attach to the headband

Three whip stitches connect the inner star’s center to the headband blank, plus one stitch at the outer ring on each of two opposite points. Two points of contact = even weight = no sliding sideways.

Halloween tips

Hot-glue a few 3mm plastic or embroidered eyes onto one point if the costume is a sea-monster version, or leave it clean for a beach-vacation costume. For siblings, cut the headband elastic slightly smaller for the infant and let the same star shape travel — the piece just carries between dress-up sessions after Halloween, which in my house is most of October.
