I use the medium size to organize cords into categories in both sides of my snake charmers when I travel. The only problem is getting them to fit easily. I don't fill them all of the way, but fold them over. I finally came up with a solution until one comes out to fit it specifically. I bought the velcro straps that Home Depot sells on the roll (black and grey). I then linked two of them together, attached them to the backside of the organizer (they cling) and then brought the other two sides around to secure the excess in the bag.

I wish I had time right now for pictures, but I'll try to do that when I do.

This works with any of the fabric organizers to make them a bit smaller to fit inside another bag.
