I would be interested in a build-your-own deal. I think that is a GREAT idea to save on postage. IDK how challenging of a project that would make for your husband to do cut outs and drilling but it still would be his design. Would they be pretty much plain? Aside from birdhouses for my local birds to use, I would love to set up a bird house "city", you know, a church, a store, a schoolhouse designed birdhouse etc.
