After my niece Ella was so excited about the farmhouse doll bed I made for her birthday, (http://ana-white.com/2011/09/ellas-doll-bed) I decided to make a doll bed for her little sister's 5th birthday. I went with the bunk bed and it was so easy to make. It probably took only 3 hours of time total (including finishing/painting). Thanks, Ana, for making me so popular with my nieces!
The bed is super sturdy. The kreg jig was invaluable. I used "select" pine boards just so the finishing would be easier. I had to use a 3/4"x3/4" trim board for the 1x1, so it was a little more expensive. Total wood cost was about $21.
I used a gloss spray paint. I don't have girls, so I never realized how happy spraying something glossy bubblegum pink can make you!
There are a couple of errors in the cut list. There should be 4 1"x1"x19" cuts for the cleats. To fit all of the cuts in one 1"x1"x8', I made the 4 cleats about 16 inches each. Also, you can't get all of the cuts out of 3 1x2s. I didn't want to run back to the store, so I left out the middle side rails on the top bunk. I kind of like the more "mod" look! (and it's not like you need the rail for safety!)
