However, I fear the 'one size fits all' mentality would be a bit harder to maneuver for a 7 year old. Plus, there's no cool patterns available. So using a variety of sources and patterns I found online, I made this one for Paige:
Here's a closeup of the top. The colors are just her style and it's sized nice and roomy for her.
Fleece doesn't fray, so there's no need to finish all edges, but I ran a small hem around the entire perimeter to give it a more finished look.
This is the fleece I'll be using to make Blake's 'Snuggie'. Lessons learned on the first - I think I'll reduce the space across the chest (between the sleeves) and a little bit of the sleeve length for his.
I hope they like them - and actually use them! Now to put them away to hide until Christmas :-)
