To cover up the button hooks, and to add a cartoon feel, I cut out circles of stiff felt and attached them with large safety pins. After Halloween I am going to sell the overalls to a kids secondhand store so I didn't want to permanently attach anything them.
And here is little Westin's Toadstool costume. I bought him a white long sleeve onsie and white pants. Again, I am going to decorate them somehow for Christmas or Thanksgiving to get use out of them.
The jacket is made out of Fleece, I didn't even finish off the edges. The yellow trim is double fold bias tape that I sewed on.
I am so pleased with how they turned out and can't wait to post pictures of them wearing them tomorrow evening!
