I've been keeping my ribbon in this little suitcase. For years it worked just fine, but lately it has been so full, it is hard to close and really hard to see just what is in it.
Jen at Lipstick and Laundry has 2 great posts about ribbon storage - one in a thrifted magazine rack and the other about ribbon wrapped on wooden clothespins.
I stopped at Dollar Tree and found these pins for $1 for a pack of 20. I used 2 1/2 bags. You will probably need more than you think.
