Scrappy Potholders is what I have made with some oh so tiny scraps and some strips.
I used a double layer of batting for these. This is the only way I have ever made potholders and they always work just fine!
I have a huge amount of tiny scraps that I sew together periodically and make up potholders. Seriously, one can never have enough potholders. I have a few friends locally that are constantly asking for potholders as their kids are really rough on theirs and they get so dirty. I am happy to keep them in supply.
