You did wonderful! Those are some nice hives. And you managed to get a good price on wood apparently. Thumb Up! 8)
What will you paint them with? White? Stain?
Seeing how well you did encourages me to try your techniques next spring when I build more hives. I'm going to need several boxes - some to replace a few (2 or 3) that have gotten a little worn, and maybe 4 boxes for expansion of the hive.
