Another way to make starfish is this:
Heat up a gather of glass and smash it like a maria. Cut it five times all the way to the rod (I use a 6mm rod) then heat up each lobe and using a 3-4mm punty with a small tip on it - grab the back of the lobe and pull. Grabbing the back helps ease out some of the fullness so that they don't look too much like flowers.
Ignore that ugly POS on top
