Silk Screening Friendly Tape?

[righttobeangry.livejournal.com]

I looked thru the FAQ and didn't see this, hope it's alright.

My friend used to buy pretty big silk screens and paint quite a few images on each screen. Whenever she would do one image only, she'd put a certain tape over the rest of the images so the paint wouldn't spill over. Does anybody have an idea what tape would stick and then not peel off the emulsion (this has happened to me before)?

Thanks!
