I found two sites offering photos and how-to-dos. The first is Homework and the second is Nap Time Crafts. Here's what they came up with:
I like that each one is a little different, depending on what type of yarn you use. You could make a whole bunch of differnet one. No two carrots look the same, right? And seriously, I think one could whip these out during a nap (not yours...your kids! Silly).
Enjoy this healthy decorating treat. I just hope the Easter bunny doesn't hop away with them!
