Take a look at here:
I 've not explored its full potencial yet...I mean....dissolving the color advertising letters on plastic bag outer surface using some nail polishing remover on a cotton ball for example...or painting them with Ranger alcohol inks and/or STAZON ink pads/reinkers... even nail lacquer as I 've seen this guy doing on xmas ornaments....
I know it seems a messy tecnique but I think I'd like to try it....mostly for the red nail lacquer hues...just painting the nail lacquer on some fused plastic flower petals....to embellish a card.
In order to cut the fused platic sheets I've used a very sticky mat...and/or some blue tape/painter's tape to adhere the fused plastic sheet (it can become a bit wavy after the plastic bag are fused) on the cricut mat....knife: 5, pressure: high, speed: high...in order to cut these cartridge simple designs. It cut like butter.
