Depends on the size of the cubbies you are working with and how much space you are willing to give up in those cubbies. The ones in the cutting/craft table I made from Ikea Expedits are 13 x 13 x 15", so I didn't want ones that were 11" square - which I found just about everywhere, lol.
Here is a link to my table:

The storage bins are ones that I ordered from Amazon. They are reasonably priced and surprisingly sturdy.

The plastic multi-level storage containers are actually ornament boxes, I ordered them online, too.
The wicker baskets that you can see in the front shot are from Michael's, and are ones that I had but will replace. Like the design, but as you can see, they are much too short - wasted space!
