I have a lot of dies which fall out the original packages, so I made a folder to hold them.
Step 1: Prepare
I took some scrap cardboard and cut 2 pieces 15x21cm. One piece of 4x 21 and two pieces 15x4 cm ( to make it extra safe, if they fall out, this will hold them.
Step 2: Create the Book
Glue the parts with tape, leave some space, the sheets with dies will be about 1 cm thick.
Step 3: Inside
Cut the magnetic sheets a little smaller than the outside 14x20 cm and tape together
Step 4: Put Together
Glue the magnetic sheets with the sides that don't stick together and glue into the book.
(As you can see I decorated first, but it's better to put the book together first, for an easier/ prettier finishing)
Step 5: Decorate Outside
Cut some nice paper in pieces 14x20cm and glue to front side, inside and the little pieces at the top and bottom.
Step 6: Finished
The result, 8 pages where I can put my dies.
