Cut 2 pieces of cardstock that measure 10" × 8" then score at 1" and 2" on each side of both pieces.
Following the photo above remove the corners as shown by the hatched areas. Next apply adhesive as shown below
Next create the box . Then cut the hinge piece and side pieces as below
Atattach the panels and hinge as below
To create the corner covers I used a 1 3/2" circle punch that I then folded and cut as below.
The handle is as below.
I applied adhesive to half the flat area of the handles as below
I then made the tab that I used to hide the thin magnets that I used as my closure.
Well I hope that all makes sense and is helpful ☺
