I don't think that is a safe assumption, that "most" beekeepers use plastic foundation or variations thereof. Many of us, myself included, will not use plastic foundation, or even plastic frames. Personally I don't want to go thru the hassle of trying to get the bees to draw it out.Yes letting the bees make their own is best but don't most beekeeper use plastic foundation now? It looks like several patents are out there. Just curious what the industry would think of it.
