I would like to share my way of cutting fabric threads that seems to lessen all those little thread stubs that can stick out from Klosters or Buttonhole stitches that have had the fabric cut away.
Take some scraps of even weave fabric and draw a line on it to be a guide for stitching Satin stitches. After stitching the Satin stitches, cut the fabric with the right edge of the scissors next to the stitches, then cut some of the fabric with the left side of the scissors next to the stitches.
After this experiment you will see that the fabric cut with the right edge of the scissors is going to be closer to the stitches. That is because it generally has a very narrow cutting edge if they are fabric or thread scissors, and there is not another blade between the cutting blade and the fabric you want to cut.
If you look down on the blades as you cut on either side of them you will see that the left blade is going to be in the way of the cutting action so that any cut you make on the left side of the blades is going to be a blade width further away from the embroidery. ©2003, Linda Fontenot, www.AmericanFolkArts.com
