This is an example of what I have created using reclaimed pallet wood. This tower stands just over 16", is just over 6" in diameter, and as you can see, is in a hexagon shape. The tower holds 42 clips with seven clips per side. The rollers on the bottom allow the user to roll it out from a back corner on the counter, no dragging. I sand everything to 320, inside and out. I stain and poly the inside before assembly taping the joints. The outside has two coats of poly satin over the stain. I wet sand between coats. Each hole is 1-1/2". I have sold 15 of these in the two years, lots of fun to build.
