I have had making a coat stand or coat tree on "my list" for probably 8+ years. You know, one of those things that you think, "I really should make a coat tree, it will be a good seller and easy."
After hubby brought home some 4" x 4" fence posts, I finally built one.
It was fairly simple construction. I used nice, straight 2" x 4"s for the base. I cut one 18" long and then two that were 7 1/4" inches long.
I used the Kreg Jig to attach the two shorter pieces to the longer board. Braces cut at 45 degree angles secured the 4" x 4" fence post to the X base. It is very sturdy.
