Wendy, I toss away any scrap smaller than a 2.5. Over the shoulder and into my bag of scraps for dog beds I don't have the style of Eleanor Burns but I sure like cutting as I go. I lose track of how many 2.5's I have but really....who cares. I just keep using them with the goal of emptying my big old "31 bag: by my September birthday. Most years, I get close to it.
It makes me happy to see all of the dear little gems being turned into warm snuggle quilts.
