My father, who is 88 years old, has discovered the world of loom knitting. He would like to make scarves for all of his grandkids and great-grandkids. We have tried to follow the instructions for the rib knitting pattern but can not figure out how to do it. The pictures are not that easy to see what is what nor can we figure out how to come back down the loom once the initial stitches on are the loom. Are there any clearer instructions out there?
