Please specify a method for die-cutting thread bobbins at home?
I like the antique styles. I'd like to use my own printed cardstock. I've not been able to find any suitable dies for/from the systems at crafts stores. I have an old 13-lobed Star [brand] thread card on hand and pictures of other styles in antique needlework magazines.
I'm wondering if I asked in the wrong category. I do want a home-method, rather than industrial that costs more than a used car, or to learn that that's the only alternative.
I don't want to remove the question because others may've wondered also. Earlier this year I learned that Sizzix now (2017) has a "die" for cutting for antique/vintage style thread bobbins (the sort embroiderers use for storing partial skeins). Now I need a economical source of acid-free cardboard. Must be acid-free in core as well as main surface.
