Hi, just taken a CND foundation course in Marbella, Spain. When doing my training I did not have a problem with airbubbles in beads, now all of a sudden they've appeared in the overlays I've been doing! What am I doing wrong? Also, the weather has hotted up down here and I've found the L&P setting too quickly preventing me from smoothing. What's the best way to store the monomer in really hot weather? Would be grateful of any advice.
