I have a skein of this yarn (sometimes called “bobble” yarn) I bought in Saltcoats in 2008 but I could never figure it out. What also delights me about this video is that it’s a man doing it! Yay for men who knit!!!!! Now, I just need to find out if he has made videos that show how to cast on and cast off with this yarn.
Michael doesn’t have videos showing how to cast on or off with this yarn, but I messaged him on Youtube to see if he could create them.
Casting on is accomplished with using regular yarn of a similar or same colour for the first row. It makes it much less complicated. The stitch used is a garter stitch – every row is knitted. It would be too complicated to try and mess with a stockinette stitch (where you knit and purl alternate rows), and doing that would make the scarf roll inwards.
