For a while I was thick into the leader ender thing, and have a fair collection of them for a scrappy quilt. But then I got the new machine Aria which has a thread cutter and does a wonderful job of not eating fabric at the start, and stopped using the little scraps of fabric. I also do mostly chain piecing when making a quilt, so don't need them. I find the newer machines don't eat the fabric at the start like the older or cheaper machines do. My little Rachel machine I take to classes is notorious for eating the fabric at the start, even the first leader, so I usually have an ender under the needle waiting for the next piece of fabric.
