When my husband first built my new craft room i couldnt decide how to store my dies, i initially had them in a box that i had to pull out and flip through, then i had them on this cube on the floor that i kept gettting stabbed by the pins and almost lost an eye searching for something.
then i built the cube on a stand that i could wheel around to where i wanted it, but it kept getting in the way.
And finally one day while browsing pn pinterest i saw something similar to what i found to be my solution, this guy had used it for storing something in his tool shed, i decided, this is it FINALLY!!!
A frame hanging on the wall takes up no space at all and i just added sheets of peg board with little hinges and in between i added board that i glued magnetic sheeting to so i could add the dies that cant be hung.
for the ones that i could hang i just used swag pins as they dont protrude, as you can see there are loads you can store on this solution and i have also spaced them so that i can keep adding to it, he he.
