Dry transfer

I'd like to help, but I'm not certain I understand what your problem is...

with all the dry transfer sheets i've used the decal is supposed to stick to the thin sheet. The thick sheet is just a backing. You'll probably notice one side of the thin sheet with thetransfer attached is slightly sticky. Take the transfer off the backing, put the sticky side down on the model in the right position and then put a drop of water on it and rub lightly until the paper comes off. Thats if you have the kind of transfers I'm thinking of.

hope this helps

Sounds like the decals have been transferred to the protective sheet somehow, if they have you wont be be able to use them and therefore up for new ones.
