The most recent successful addition to my scraproom is a box of tissues. Not a huge box, one of the 'boutique' sized boxes. I didn't know how much I'd use them until I put them on my table. I will need to replace that box with a full one sooner than I thought.
Being a penny pinching crafter, I take the time to cut sheets of paper towel into quarters and put them in a stack, instead of tearing sheets off a roll. It doesn't take long because I use a big rotary trimmer and go through six layers at a time. The squares work better than the stamp scrubber pads I've tried to keep my stamps spanking clean.
An alternative to cutting up tissues and using smaller squares is toilet paper. Nope. My brain just shut down and refused to function. That is where I draw the line. Tissues. Tissues are good. Perhaps I'll create a cover for the box out of chipboard and patterned paper.
