My wood ones are on thin shelves organised in 5 major areas :
1. kids, people, animals, fairies
5. Flourishes, scripts, sea and backgrounds
So easy to find things as they each have their place.
People, kids, animals, fairies on the left panel, Christmas on the right :
Background, flourish, scripts, sea, sports :
My clear and cling collection are not so big, so they are in 2 shoe boxes with divisions : flowers, patterns, mixed messages (words and pictures), words, alphabets and Christmas.
I had started an inventory file, but got too bored stamping them all out . . . I'd rather be creating. So I stopped.
And I'm happy.
