I've been reading a lot on the subject and want to get started in this artform. I tried my first batch last night using a recipe I found. Working with the material I found that it took hours to harden completely so the flowers I made wilted and didn't look very happen lol. What might be the cause of this? I also made a bow and the curved portions ended up deformed after an hour. So I am thinking something is wrong. thanks in advance!
