I moved the injection hole (as mentioned in Mask Making) to the tip of the nose. I’m so glad I did, because I finally got a full mask! There’s only one small hole, which I’ll be able to patch.
I think the hole was caused by not sealing the original injection hole.This reduced the pressure on the foam as it was being injected, and made it more difficult to fill the mould. It also wasted product, becasue a lot of foam escaped from the hole instead of filling the mould.
Once the hole is patched I need to trim the mask down and paint. It’s so close to done now, I’m really excited!
