I was just about to post eyelash glue but looks like someone beat me to it. I've used it before and it works pretty well as long as the pasties aren't super thin because the clue can kinda seep through very thin fabric. But If your pasties are made of somewhat substantial fabric, eyelash glue will work. Well, actually, it works with the thin fabric ones too. I mean, it'll stick. But I used it with a pair of very light silvery colored ones and you could kinda see the glue a little bit, even though it dries clear. So if they're darker colored it might not be as noticeable. It still works though and the appearance of the glue will just be an aesthetic choice you'll have to make whether it's worth it or not. Definitely cheaper than paying a boatload of shipping costs. Spirit gum would probably be kind of a pain because it's thicker and kinda tricky to apply. It can also burn on sensitive skin. I can't use it with anything too close to my eye area or it stings pretty badly. Eyelash adhesive is made to go around the eyes so it's fine on sensitive skin! And, will clean off a lot easier than spirit gum.
