Hi- I have large crocheted earrings that nothing will stiffen sufficiently. I want to try resin. I do not want to “encase” the crochet in resin, i just want to stiffen it. I do not want the holes to fill up and I want the cotton to stay as close as possible to its original texture. I want them as close to the way they look before adding resin as possible and to be 100% stiff and flat. What kind of resin should i use and is there a way I can thin it with so it absorbs into the cotton as much as possible? Thanks!
