I discovered Whip Up recently while trolling the interwebs looking for cool things. One of the things I like about this site is it is not so overly-precious as some of the craft sites are and projects tend to be easy and doable even for the novice crafter. The full name is Whip Up, handcraft in a hectic world.
That makes it a great site for families anytime, but this month they are especially focusing on crafts for kids with a Month of Crafts for Kids. They've already posted a bunch of fun stuff like these worry dolls and these winter glove puppets.
