I'm cutting some comb from a dead out Warre (that I've not been pleased with) to help seed a hive for a new package in the coming weeks. I'm going to rubberband the comb into some foundationless frames. How picky should I be with selecting comb to put in there in regards to straightness? Some of the combs are a bit wavy but I'm assuming as long as things are reasonably flat once in place I should be okay. Thoughts?
