This was my first attempt at building a bed. My wife wanted to buy my 2-year old a twin bed from one of the big box stores. I asked her to let me take a crack at it before she spent several hundred dollars (and hours of assembly for me!). I immediately went to Ana's site first and found this plan. Since my wife loves all things PB, it was an easy sell.
I spent about $75 on lumber at Blue and about $20 on hardware at Orange. I also used this project as an excuse to buy a random orbitsl sander, so altogether, I spent less than $150. The mattress is a Serta Benson that we picked up for $180 after taxes and a Black Friday special. It came with a free box spring, but I declined because I used slats and didn't want the bed any higher.
I followed the plans in terms of measurements and dimensions. However, I modified the headboard and footboard. I omitted the cross pieces on the headboard and used quarter-round pine trim to hide some imperfections on my plywood cuts. I think it turned out OK.
