Heres a box i made today out of material that Hubby's plant threw away.
He figured i could make something with it. Its some type of board. I
really don't know what its called. Its 1/4 " thick 32" x 40".
I saw someone had a tutorial on how to make this about a month ago. I really
can't remember who. But I think you can find a video on YouTube for it.
I used just one of the board sheets. Thin flour sack cloth and double sided
tape and masking tape. Also a sheet of 24 x 12 white paper from Provo Craft.
