I made these with 8º and 11º beads because I don't have access to 10º easily. Not sure if that's the issue (maybe I didn't pull tight enough? idk), but mine are a slave to gravity. Soon as I don't have it on something flat, it loses the proper shape and the bottom two points get squished. :\ Which is a shame, because I love these. Gonna take it to my local bead shop and see what she thinks, but I have a feeling I'm going to have to put little dabs of glue at the junctions so that gravity is taken out of the equation.
