My friend Ann in Colorado invited me to join her knitting group (via Zoom) one Friday afternoon. Everyone was knitting a woolen piece to be Felted into a bowl. it was fun to knit with them , virtually.
You have to use large knitting needles and 100% wool yarn to be sure it will felt. I was trying out Germantown yarn worsted by Kelbourne Woolens made in the USA. Our local yarn store, McWalker Yarns , had just gotten some in stock. I chose one 100 gram skein of Sage Green.
It took me a little under two hours to knit. I ran it through the front loader in hot water with old canvas sneakers, twice. A top loader is preferable for agitation and a quicker result.
Note:There are free knitting patterns to search online to make felted bowls. The pattern I used is in a book so can’t copy it.
