The Simplest Solution

Circular needles come in different sizes and different lengths.  They get tangled up all the time when left to their own curling devices.  My simple storage solution was to get a small binder (7 x 9 ) at Staples with some plastic page covers.  I wrote the needle size and length on the outside with a Sharpie.

Of course, I could keep the whole thing closed with a rubber band, but I hot glued the remaining ribbon on the back and now it's organized and fun to look at.
