I had the same problem. I finally tried SU glue stick and just glued the daylights out of the cardstock and it finally stuck. I had to go back to a few places and added more adhesive. I also added the glitter after all the layers were glued together, because I kept smirring it everywhere. So now I just adhere the dryer sheet, glue everything to place and then add glitter and spray with hairspray to keep it in place
I hope this helps some. Don't give up, I am doing this today for my club and I know they will love it. The hubbies will also love it considering I am specifically telling the wives they need to do LAUNDRY first before they start stamping for this technique, ha !
