I picked up the wood this morning and just finished measuring and marking all the required pieces. The guy who sold me the wood cut the 1/8 inch plywood backing to size for me, but I could have just used a utility knife, I think. My sawing will be limited to making crosscuts with my neighbor's table saw. We just cracked 100 degrees and it looks like it will get hotter still. The raven is watching everything from his high perch, complaining loudly. This is going to be fun.
