The cube is sturdy and helps me organize all my quilting tools and quilt projects. I had a slight problem with aligning the guides with the holes in one cube (one out of four cubes). An adjustment to the hole and everything is great. I stacked a cube on top of the other and attached casters. It now can be rolled to my sewing machine where I use the top of one for ironing and the top of the other for rotary cutting. My sewing table is higher then the normal height of a table.
