I've been wanting to make one of these sewing jars for years.
I made this prototype tonight. I have a whole box of these canning jars that I think I bought to store homemade yogurt in, but never used them. I'm not sure I'll make anymore of these, but if I did, for my shop, I'd think of a better way to finish off the inside of the cap. I just popped in a circle of scrapbooking paperboard with the look of old lettering on it.
Sometimes I go wild with something and make many and other times I just make a prototype and keep it for myself and move on to something else. I'm not sure how others make them, but I cut a styrofoam ball in half to use as the pincushion top. I love hot glue...It makes crafting SO easy.
