Thanks everyone. Depending on who you’re sticking to what surface, these are great options. I ended up buying most suggestions here, and they’ve all worked great for various layout locations.
As a side note Home Depot stocks, in the store, museum wax. Although it’s in an enormous 13oz container, it’s only $10... If anyone in central PA would like a scoop or two, I now have enough for many lifetimes.
