After having had some trouble with two recent stitches, I was very pleased to learn this new one, TAST #138 Barb Stitch. It was easy peasy and I am very happy with the result.
I have just realised that our teacher, Sharon, has worked her whipping stitches from right to left so the centre stitches are slanting in the other direction. Actually I don't think it is so important, and I won't undo my left-to-right-whipped stitches... You, however, who probably will read the instructions more carefully, can learn the correct way from Pintangle. Have fun!
