In my seemingly never ending organizational quest I purchased 8 of these bins at Lowes, stacked 4 each on top of each other then placed them on top of the wooden furniture dolly’s for easy rolling in and out. 2 fit perfectly in an unused narrow deep area, and I covered the bins with a crib sized sheet. Bolts of fabric are a perfect fit! Eventually I will tweak them with wood around the bottom so they don’t move at all when I pull them out. The shelving unit is perfect for 26 clear plastic containers and 10 smaller ones. These were under my long arm and had to be moved when my set up changed. My goal for the next year is to work on my 5 large totes of scraps and get those organized.
