Note that all the examples have designs merged on them! The files here are blanks, awaiting merger or fancy vinyls.
Being able to mass-produce keychains is handy if you want to use them as freebies, or have an inexpensive booth-filler item at craft shows, or make a bunch for a team or other group.
The octagon shape and tab mean these are all nice angle cuts, quick little chops with duckbills or rag-quilt snips. There are also small square options, with or without rounded corners.
There is now a quarter-keeper option: the octagonal blanks are preceded by a set of buttonholes. Stitch those on the backing sheet, unhoop it, use a craft knife to cut the coin slot, and use the registration marks to align them before the final stitch color. Or leave it hooped, cut the coin slots, and put a fancy vinyl on the hoop back instead of stitching a design.
They come in 5-up (4x4/100mm), 7-up (140mm), 9-up (5x7), and 22-up (200mm) formats, and both the square and octagonal tabs use the same layout so once you have designs laid out they'll work on both types.
