Worbla is often used to create full suits of armor, but the material is also great for accent pieces. Cosplayer Sarcasm-hime used Worbla for the first time last year to make the headdress and spine for her Moondragon costume, and she was pleased with the results. She specifically chose it since she wanted to do cut-outs and there’s no internal mesh present in Worbla. She documented the entire process with words and images. Here’s how she handled the cut-outs:

I first drew the pattern out on the Worbla using a permanent marker. I wanted a sort of random, organic pattern so wasn’t too fussy about this part. The hot-knife made cutting through the 2 layers of Worbla fairly easy; it didn’t take as much brute strength as it otherwise would with an x-acto knife. The hot-knife slides through the Worbla fairly smoothly with a little pressure. However, because the hot-knife is actually burning some of the Worbla as it cuts, I strongly recommend doing this outdoors or in a well-ventilated area. I had to work indoors as it was too cold outside, so I bought a respirator mask designed for use with paint fumes.
