It really depends on how the earrings are digitized. Here are some instructions for those digitized for vinyl. Instructions are also included for stitching on organdy or tulle. Have fun making them.
Some of them also have to be done on something like tulle as they aren't all free standing.
Only the "hanging" part is mad out of WSS for lace earrings. You must buy the hooks and any jump rings and put together. Hope this helps. Betty
