We have a lot of left over crafts from previous projects I've made with my girls. You know what most households always have too? ODD socks! God knows where the other one went, but there is always a bunch of socks without a partners in this household. This is really easy and you can find a BUNCH of youtube clips on how to make these. How do I know that? Because that is exactly what my girls did. Looked it up then asked and away they went on their own. Ugh they are getting older.
To make the filling, Heidi got my thick wool and a brush to tease it. I didn't even know this, so even I learnt something new. My girls are good around a hot glue gun and if they have any issues they always ask. So if you have younger kids this may be the only thing you'll have to help with. They've also used wool to make the icing effect on some.
What will they do with them? Heck I have no idea. But it kept them creative, entertained and they had fun during the process. Beside those socks were only going to be thrown out anyways. The results are SUPER cute!
