Just got my Flexi-Glass medium and sheets in - cant wait to try it out - its developed by David Acala - the glass tapestry artist
Looks like so much fun
you liberally apply the medium to the special clear sheets - fire at a low temp (200 F) and it pops off the sheet and you can cut it up or you can mix and create threads to apply to other pieces etc...
got at Fusion Headquarters
interoduction to flexi-glass from Delphi Glass where you can purchase as well
