I think having the option to buy individual plans for $10-15 is great, but also maybe an option at a discounted price over purchasing all the plans individually, the whole set. Or maybe a discount for purchases of multiple plans. The first coop I built I made from just a photo I found online and had to figure out all the measurements and cut list as I went along (and made plenty of mistakes along the way!). The second one I'm planning on building I purchased the basic design and materials list, but it doesn't have a cut list. It would be nice to have all the directions to work from.
