I bought several Univenture 3-ring 1.5" binders when they were on clearance ($1.09 per binder...wish I had bought more!!!). The outside dimensions are 7" x 9 3/8" x 1 1/4".
I cut the magnetic sheet into strips. You can cut them however you want (like covering the entire panel). You could just use the magnetic sheet without the panel, but I find it too flimsy/bendy. By cutting them into strips, I get more out of them. I used double sided tape to adhere them to the binder panel.
I organized my binders by theme: shapes, frames, 3-D, borders, etc. The Univenture binders come with a clear cover, so you can design your own cover. I just labeled the spine with the theme.
I'd love to see how others organize their dies....please leave a comment with either a link or description.
Thanks for visiting.
ETA: Also, someone asked me about how I store my ink refills. I found these storage containers at IKEA.....love to shop at IKEA!!! They are the Krus containers and these were $4.99 each. They are the perfect size for a|s refills (too small for SU refills).
