We were taught the basic stitches of knitting: Knit, Purl, Stitch Increase and Stitch Decrease and told to play and make something for the body. I realized b accident that if you increase several stitches beside eachother you get holes…. and went with that. all of the holes in this piece are permanent and won’t continue to unravel it. There was also a twist in the tube when i knit it, so i knit in between it to make it a permanent part in the piece.
