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)
