I found this idea somewhere on the vast depths of the internet but it was so long ago that I can’t remember where so my apologies for not giving credit where credit is due.
I had one of those plastic boxes which had all my yarn in it. It was hard to see what I had, how much of it I had, and things were getting in a tangle. I found these CD & DVD storage units from Argos and thought they would be perfect. We went out and bought 2 of these, built them up and now my yarn is on display and so pretty. I can look at it and feel inspired. All I need now is my yarn winder (already ordered).
