My 5 year old daughter wanted to make the Christmas tree garland for her teacher. I thought it was a great idea but was totally garlanded out from making 5 of them so I told her she could sew them herself. She of course was thrilled since we haven't been doing too much sewing lately.
For full directions on how to make them click here.
Here is her version.
And here is another tip in case you don't have a small table for your kids to sew on. (Or you are too lazy to bring the one you have back upstairs for your kids like me)
Just put a box under your table and place the foot on it. Works great!
