When Ron started putting the plywood on the ceiling, he started out with 1/4 inch plywood, after soaking it with water. The first two pieces Ron put up was easy, so Ron figured he would put up all the side wood first, then come back to the ceiling...well, the next piece he tried to put up, just would not bend, no matter what he did. So, we ended up buying something called "bender board" and that stuff is just amazing to work with. Ron put the 1/4 inch plywood up to where the wall starts cuving towards the ceiling, so when the cabinets go up, he'll have something to anchor them to. Then, he put up 3/8 inch bender board the rest of the way. I didn't take any pictures of us actually putting up the bender board, because it took two of us to do it and no third person to take a picture.
