Finally I had 1320 stitches per round and needed 25 minutes to finish one single round. This makes an average of 53 sts per minute. The patterning rounds needed much more time than the simple ones.
For increases I used YO which I knitted twisted.
I’m really not a friend of written patterns so I drew the first rows oft the pattern on grid paper and marked the points of action. You may recognize now that the main action is at the beginning and the end of a quarter of the round. Once understood the principle of the rhythm you may skip the rest of the pattern.
The color combination may not be harmonic, but is matching to the beanbag of my niece.
In other notes I read of mistakes in the pattern. I didn’t find any but either didn’t look for. I used the pattern very intuitive. It’s very recommendable for using up leftovers, thank you for donating this free pattern!
