If anyone is curious.
I was curious about cutting out some of the foundation out of plastic frames. I like to let the bees build their own size comb, but I like plastic frames. In my humid weather plastic does not warp. So far so good, the bees are doing a great job blending in they natural comb with the plastic ones. Hopefully the experiment will end good. The queen even expanded the brood nest - larva in last picture

How they begin
