Nimbus Cosplay shared this method of using both the folding and sandwich method together for a smooth application without air bubbles and less Worbla used.
Tips for getting the most out of your worbla, and for smooth application without pesky air bubbles!
You’ll end up with more tiny scraps that you can heat up again later for detail sculpting, and the insides of your armor will look a bit neater, and be less bulky around those edges.
After the outside is nice and neat, I cut the inside sandwich piece actually a bit smaller than the shape of the armor, heat it up separately (doesn’t really matter if you overheat that one) and then just lay it over the inside (more pics later). This alteration to the sandwich method also makes it easier to more precisely apply any connections inside the armor (D-rings, clasps, etc…)
It should be noted that this will take more time since it’s a more tedious process than straight sandwiching. So if you’re in a rush to finish something before a con, you’ll probably just go with the traditional sandwich method.
