The drawer I keep my wraps and storage bags in fits everything pretty well, but my sandwich bag box had space behind it, and would keep sliding to the back of the drawer.
I had been looking for something to put behind it for a while, but getting something just the right size was proving to be difficult. But I finally discovered something that worked: cut-to-fit cardboard packing material!
It works famously!
Oh, I applaud that! Re-using something at hand and making it work? Fantastic! (Also, I recognize that little yellow cardboard knife. 🙂 )
