Go to your nearest wally world and get a bottle of Fabri-Tac!! It is so much better than tacky glue and it will hold those on with no issues. I make dolls and use that to hold on eyelids and lashes and have even used it for attaching lace and such to outfits! It bonds fast and dries clear!
I second the recomendation for Fabri-Tac. That stuff is awesome. It can bond fabric to fabric, fabric to wood etc. It is kind of pricey, but a little goes a looonng way.
