I just read that again. Ignore the "turn" instruction. I think that's what's screwing it up. If I'm reading it correctly, you should be crocheting a circle flat, and then working up the sides (with the 1 in 1 and then 2 in 1). That will get you to the fat part of the pumpkin. You do a round, join, chain, and then do the next round.

ETA - The only way I can think you should get that if you increase in a circle is if you're doing about 10 stitches in one - it really looks like there are multiple edges.

It is a cute pattern!
