My mother and I used to roll beeswax candles, and not only were they really fragile, but we had to take melting into account too! (We rolled like mad in the spring, when it was warm and humid enough for them not to crack, but not SO warm that they'd be sticky!) We routinely had folks ask us to mail them, but wow - we'd never even try, knowing the likely results.

How about a link to your etsy store so we can all ooh and ahh? (I can't order at this point, but I'd love to bookmark it!)
