Alternately, get some beeswax, then get a used crock pot from goodwill, put the wax in, when it's fully liquid, start stuffing scales in. Leave each one in until it stops bubbling, then remove it with some tongs, and give it a little shape with your hands (wear gloves, they're hot), then let them cool. Hard like wood. Don't leave them in long enough to scorch, experiment with scrap first.
