foldedbird, great tips! Thanks!
Hildegard_von_Knitti, I thought varigated yarn would be confusing, but you've got a great point!
I'm going to give them all some copies of a couple of pictures of knitting and purling next week. Hopefully that will help them when they are working during the week. I may have to make a deal with Amy so they can all have a copy of her great videos!
