I am making a cake mimicking one of Lady Gaga's dresses, an origami crane dress.

See the cranes on the side, I figured out I need a heart shaped cut-out, roughly 22 cm across. I made my gumpaste yesterday, and today I attempted to roll it out. BIG PROBLEM. The gumpaste roles out to about 1/4'' of thickness before it starts drying out and it stops stretching and gets tough.
How do you recommend I get such a large cut out? Should I use tylose + fondant instead? Has anyone experimented with pastillage? would this work out for this? Keep in mind the heart shaped cut out must be folded and glued.
Any help would be appreciated!
