This was made from Anna's Farmhouse bed for dolls plan and the trundle plan. I bumped out the dimensions since my DD has a "My Twinn" doll as well as American Girl Dolls and the My Twinn is a few inches bigger.
It was hard to find bearings for the bottom of the trundle so I used drawer runners instead. I also made the trundle first then sized the bed to fit around it. I added a facia to the trundle for decoration with mitered side edges to give a "lip" to pull the trundle out.
This was my second project, made on my first project... the workbench!
