To add to what Slick mentioned, I also put a cover sheet of some kind on the bottom platen of my heat press after pressing one side. I don't want any glue to seep out around the stones and stick the the platen and then melt onto the next shirt I press.
So start to finish:
I press the first transfer with a cover sheet.
I peel the transfer tape off.
I put a Teflon sheet between the shirt.
I put a silicone sheet on top of the bottom platen.
I press the second side with a cover sheet.
I peel the transfer tape off.
I press the second side with the cover sheet on top of the rhinestones for another 10-15 seconds.
The reason I press again after peeling the tape off is to set the stones more and also because it helps to get rid of the rectangular line around the design that the transfer tape left.
