/cgl/ - Cosplay & EGL

Sharing my latest work (it's a brooch). Any advice on materials for the base? I made a base out of an ordinary thick cardboard, but I hate it since it's difficult to cut precisely and it tends to split between the layers.
Also, sharing a tip: don't fucking buy Padico's "Decollage Coat"! Such a waste of money, I'm truly disappointed. It's just an ordinary decoupage varnish, and it sucks compared to Mod Podge or Decopatch. I'm really mad with it since it fucked me a piece up when I totally wasn't expecting this.
