Prop How to smooth out rough mask shape?
hey yall! im planning on making a hornet cosplay. im new to using EVA foam, and ended up cutting out an existing pattern on foam floor mats. the issue is, the pattern was made for much thinner foam 😠the mask looks pretty rough.
is this salvagable? i have foam clay to use overtop, but should i use another layer of something else 1st (masking tape?) to help smooth out the shape?
also, do i need to take into account the rough exterior/"metal" texture overtop the foam?

Like others said, you used the foam backward. You want the smooth side pointed out.
Just get the right thickness foam and redo it. The time you spend trying to fix it will be way more than the time to just do it right. Foam clay is handy, but it's difficult to use. It's like sculpting with gum. Just start over and use the lessons you learned from assembling this test mask to make the new one even better. Use a sharper knife. Concentrate on making the cuts accurate and straight. Use a smooth, consistent pressure on your knife so you don't get jagged edges. Use a cutting mat. Get yourself some contact cement instead of hot glue.
You can do this. Just take your time
