Some years ago I was at Staples right before closing time. When checking out I overheard one employee ask what to do with all the boxes of paper rolls stacked in the back. The manager said just dump it before you leave. Well, I talked my friend to going back with me later that night. I thought it would be rolls of craft paper. We found three big boxes full of unopened packages of three rolls each of adding machine tape all different size widths. We got them all. This was when I first found out about strip sewing on the rolls. I stocked our guild closet with tape and it's still being used today.
