Hi! LuKaStOkA
Becki says how she shrank the plastic in the oven on the first page of this thread about 12 posts down. A bit trial and error, but worked for her!
Is this what you mean?
It’s usually done by buying the shrink plastic, stamping a pattern on it and colouring it, and then holding it down with a cocktail stick or something while blasting hot air from the heat gun on it, which makes it curl up in all sorts of ways, but it usually shrinks out evenly. Then finally flattening it with the flat back of the stamp before it cools.
Hope this helps! But If you knew it anyway, it probably didn’t.
If you get SKY, Channel 671 (Create and Craft)is back-to-back craft workshops and it’s bound to come up. You can also get it on computer.
Cheers!
