I made these for a friend, her husband, and their almost-here daughter. Some of the pictures, therefore, show more parts than are needed for one hat, but for simplicity I'm going to write it up as just one hat. So when you see a pile of six ears, you'll know it's not a six-eared bunny (not that there'd be anything wrong with that) that later dropped 4 of them, or anything.
- 3V coin cell battery
- 2 red LEDs (cheap crappy Radio Shack kind are just fine)
- 1 big white turtleneck
- white felt for backing
- pink felt for nose, ear insides
- regular thread: white, pink
- conductive thread
- little bit o' stuffing
- hand needle that fits the conductive thread
- needle nose pliers
- sewing machine
- tape measure
Step 1: Cutting out ears and hat
Draw a hat pattern on the bottom of the shirt: a rectangle a little smaller than the circumference of the head it's for, with four triangles along the top. The triangles create the rounded head shape, and give us someplace to attach the ears. Cut this out with a little extra around the edges for the seam.
Cut ear shapes out of pink felt and fabric. For each ear, cut 1 felt and 2 fabric. Add seam allowances around the edges of the fabric - I didn't do this and had to cut the felt down a little afterward. Benefit from my error!
