They look great! I'm in agreement with everyone here, I would've never thought of that. I'll have to be on the look out for these type of boxes on the cheap. They'd be perfect for a little "kit" sewing, cooking, tea, etc.
Thanks guys. I was so happy when I saw this in the book, I always save my vinyl bags but never knew what to do with them. Now just what to do with the rest of them I think I'm going to use some of them as makeshift "glass" for frames.
