Here's how I made it:
Step 1: Fill your sock with dried beans. You'll want to fill it just above the heel.
Step 2: Tie off your sock with a rubber band. You'll want to pick a color that blends with your sock.
Step 3: Cut the cuff down to the rubber band. Hot glue the side seams (see where my white dots are) but leave the top seam open. Pull apart a few cotton balls and stuff down into the bunny ears. Seal the tips of the ears with hot glue. Oh, I didn't do this, but you could put a pipe cleaner in each ear to make it bendable.
Step 4: Now add eyes and a nose and tie a bow around the neck (you'll have to push around the beans a little). I used scrapbook brads with the stems cut off for his buttons, but you can use anything. I painted on the whiskers with white acrylic paint. You could add silk flowers to the ears, real buttons, ric rac ~ pretty much anything. Oh, don't forget the tail! If you want a smaller bunny, just use a pair of kid's socks.
These are really easy to do!
