This was a simple project to create a perfectly-sized utensil holder for our odd-sized drawer. I never liked how our current one bounced around in the drawer. I wanted something that had a tighter fit and was better organized than our current mess.
The sides were thin slices of poplar (leftover from the kitchen cabinet project). I cut them with my bandsaw then smoothed them out with the sander. I cut out notches to create a tight fight with the crossbar. The ends I left as simple butt-joints to not overcomplicate the fit. I also expect the drawer itself to help support the edges.
