I make my own foundation and it works well as it is embossed. The apparently hit or miss experiences of non-embossed sheets would make me think that using it is not worth the risk. There is nothing nicer than a colony with well drawn out comb as it is so much easier to manipulate than a mish-mash of comb which may be warped, full of holes and aberrations where they can hide queen cells and brace comb. Keep your beekeeping as simple as possible - the bees will set you enough interesting challenges without your inventions, interventions and experiments!!
