For most of my hand sewing I usually end up grabbing my betweens regardless of what hand sewing I'm doing. They are generally the handiest to me. Unless it's a really odd project. I use betweens for running stitches; quilting; stitching binding; hemming pants; you name it. I use Roxanne betweens normally either size #10 or #11. I do have some #12's but they are really, really tiny!
