Any good tips for neatening Worbla edges on thick props/items where both sides will be visible? The majority of tutorials either deal with just one-sided armour or gloss over the problem entirely...

I've heard of using strips along the edges and then a soldering iron to help smooth them out and blend them, any thoughts?

pic semi-related, need to wrap a thick eva foam shape and keep it neat on both sides
