I was recently working a Knitweave stitch pattern and found loops at the edges of my knitting. They had caught under the carriage at one point, so I removed the carriage and took a peek under the wheels and brushes. To my surprise, not only was there yarn wrapped around one of the brushes, but I found "fluff" underneath one of the wheels as well.

I put everything back together and tried again, but I was still getting loops.

It turns out it was a rookie mistake!
