So I decided to make one. Took me a few hours, but worth it! The size is 6 1/4" square and the height is 3 1/4". The box holds 25 inks or stickles.
I used chipboard which I adhered together using kraft cardstock hinges using Scor-tape. I then covered the inside with paper, then decided to collage some DCWV "Once Upon A Time" papers on the outside.
The dividers inside were also made from chipboard, painstakingly cutting all notches with my craft knife. Worked well, I think.
Will be posting a video on YouTube as soon as I can edit it.
Let me know what you think.
