I just searched Ravelry and found patterns for 41 batwing sweaters. Don't know if you're looking for a pullover or a cardigan, but after you put in your parameters, type in batwing. Also, I didn't try it, but a cocoon sweater might be similar.

That you so much Donna. I'll go and take a look.

Ravelry is a great resource for finding patterns, project ideas, seeing how a yarn works up and getting comments on how it is to work with. One area where the internet has been a blessing.
