Tiff shared with us this great way of dealing with the air bubbles you get from sandwiching Worbla.
If I had a dime for every air bubble I made using the Worbla and craft foam sandwich method, I’d be retired by now. Worbla is a wonderful material to work with, but it’s so easy to form air bubbles even when you think you’re being really careful. Have no fear, there’s a really simple way to get rid of it by using just a needle!
- Make sure to use a heat gun to warm the air bubbles so it’s nice and soft.
- While it’s malleable, use a needle to poke a single hole in the annoying air bubble. You must poke it at an angle (see picture #2) so it can open the hole. Poking straight down wouldn’t be as effective I’ve noticed.
- After poking the hole, use your finger to pat it down so the air gets released.
- It should be a lot smoother and less bumpy. Sure, you can see subtle holes on the surface but it’ll disappear when you fill it with gesso or wood glue.
