and i want to glue the rhinestones on it... but i dont want the glue to show aroudn the rhinestones when i hold them down. what is the best glue and how do i avoid the glue ooze issue??? ty!!!

a6000 is good, get a paint brush to bush it on, a small cheap one. I use this glue for everything and I craft all the time

you can get it at michaels, joannes if you have joannes. Prob acmoore. any crafty store, if not try ebay
