I wish I had known about this method of casting on knitting stitches a long time ago! This is called the long tail method or the sling shot method. It gives a neater beginning edge than the traditional "over the thumb" method, making it look and feel just like the cast-off edge.
I am in the process of knitting a blanket, in squares, for a gift. When finished, it will have a patchwork effect similar to that of a quilt. I can't wait to show you the finished product........maybe this spring?
