I didn't feel like swatching and doing the knitting math, so I just went for it, adding 20 to everything. Instead of casting on 34, I CO 54. instead of knitting 34 rows for the bottom, I knit 54 (and so on for the rest of the bag) this larger booga was for my mom, and she wanted it bigger than mine, with shorter handles. she was thrilled with the results. I used WOTA for it (and size US 10.5 needles) , but since I did so many color changes, I got more balls of yarn than I would have needed, and I'm not sure how many I would have used for a solid color bag.
here's a pic of the finished booga I made for my mom:
