My son and I have been working on a travel-size sewing kit. We spray painted and decorated a large Altoids tin (one of the extra big ones that are only sold at Christmas time). We added new spools of thread, safety pins, a needle threader, a tiny pair of scissors, thimble, some buttons, and a seam ripper.
Today, Blaze made a felt needle book to go into the box. He hand-sewed the seam down the middle of the book and then machine-stitched a League of S.T.E.A.M. patch onto the front cover of the book.
