I know this sounds pretty simple, but I'm not happy with the inner covers I've been buying locally and want to look at making my own over the winter. The one's I've been buying are recessed on the top, but flat on the bottom. I'm having trouble with the bees propalizing them to the top of my supers. A couple I've had to prop up to keep them from pulling out the frames when I pry off the inner.
Anyone seen any plans with dimensions? The build it page had a pretty vague description under the 10 frame Langstroth plan.
