In a couple of my Yahoo Groups they are having a forty items in forty days challenge that starts today (Feb 6) and lasts until the end of Lent. I have pledged 40 baby hats in Bevs-Charity-Challenge and 40 crocheted yo-yo's (small crocheted circles) in Crafting for a Cause.
You don't have to be in either of these groups to participate in this challenge (Although I highly recommend both). All you need to do is decide what your going to make 40 of for charity and make one every day!
The pattern for the yo-yo's is here. If you don't want to join them yourself join Crafting For A Cause (LOL).
