Cardboard Doll House. I pinned the "cardboard tutorial" from Ikat Blog a few days back, and today I found this... I swear this is one super patient and super creative mom! Just check out the level of detail in this one. It has an elevator, stairs, a locking gate, sliding door, hinged door, curtain with loops, lights, picture frames..... O.M.G!!!!!
DIY Dishrack-- This looks like it was made with toothpicks. Instructions are in Spanish (Google Translate saves the day again!) This would work great as doll house or Barbie furniture. Bottle caps painted with nail polish would work for plates as well.
