This is very cool. There is an old story in my family that my Great uncle converted an old singer into a jig- saw, way back during the depression, and made filigree wood cuttings into boxes. It it is a true story or not, I don't know, but I do have a wooden box with an ivy patterned filigree. It is about as big as a cigar box. I love it and keep my sewing tools in it.
