Here’s the Booga Bag I recently finished. I used Noro Kureyon #51. I ended up knitting the bag on sz 9 circs because I couldn’t find 10 1/2 circs locally, and I already had the 9s.
I made the bag a bit bigger to compensate. I CO 42 sts and then knitted 42 rows for the bottom of the bag. Then I knitted about 80 rounds for the body of the bag. The finished dimensions (after felting) are about 8.5 inches wide, 9.5 inches tall, and 4.5 inches deep.
