Thanks, Ana! My main recommendation is to give more details on how to connect the three separate pieces. I ended up using two 3/8" carriage bolts on each side of the headboard and four 5/16" carriage bolts across the footboard. I also made the 2x6 slats in the frame such that my mattress is "countersunk" since we have such a tall mattress. Otherwise, the design and instructions were great.
We used Silk Pillow mate paint from Home Depot, and then did some distressing (but not much!) and went over with American Paint Company brown glaze (sponge brush with a old white t-shirt to customize the darkness).
I spent more than Ana's impressive $120, but definietely kept all my expenses under $400. Worth every penny!
