If I understand your question about "make your own" earlier I was referring to making your own frames.....the foundation you use for the frames is up to you. If you are going to small cell, that's what you would use. If you are going to crush and strain or make cut comb honey, you'll not want to wire your foundation.
Also the size foundation needs to fit the frame you purchase. I know this is a simple math question, but I have a hard time with it. I always order online, but I understand that if you use the actual paper catalog, you can see what size foundation to purchase for which frame. In the end I have never had the actual correct size, but now that I am usually using starter strips, it doesn't matter anyway since I am cutting up the foundation I purchase into smaller sizes.
I did order and put on one of my hives a foundation for cut comb that Michael recommended 7-11 from Walt Kelley. The foundation is larger than regular foundation cells but smaller than drone foundation - I've only done 4 frames with it so we'll see how it turns out.
On my way up to the mountains this morning I passed the turn off to Lula, GA where Fatbeeman has his apiary and sells SC foundation that he mills with non-chemical wax. Next time I come up here, I'm stopping and buying some of his. Actually he teaches an organic beekeeping class the first weekend of every month - so first time I have a first weekend free (I am free the first weekend in June and then not again until October) maybe I'll take his class and report here!
