I've been looking at that $20 plan and really liking it. I built something like it last June and it would have been really handy to have some clear instructions. All we had were measurements of the finished product and whatever we may remember from high school math. Needless to say, it sat a little crooked and wasn't as cool as I was hoping. Still dang nice, but could be improved upon. Thanks for any input. Pics would be awesome!
