While preparing for this challenge I had the stroke of genius to add a Halloween theme to the manicures I could (because I really can't stress enough how much I love Halloween!). So I'm now giving myself three elements to this challenge - the theme, using at least one untried, and adding a hint of Halloween. Today I succeeded!
My base is W7 Matt Pink (untried!). It does dry to a satin finish - I hoped it would, but Barry M Matt White isn't matte, so you never know! I stamped with Cheeky Jumbo plate 1 Viva Mexico, and Barry M Gold Foil and Plum. I'm a little bit annoyed that my gold skull is a little bit too far down, but I'll live with it!
