If you'll send me the picture in an email, I will post it for you. Is it knit or crochet?

Here it is:

I'd think you could use any sweater pattern you like...and simply make the sleeves short. I've done that with the basic v neck pattern from THE SWEATER WORKSHOP...but, really, I'd think any pattern would work.

Well...I'm not that good at knitting...but I'd think that you'd have to have the right gauge..equivilent to the cotton and not worsted yarn. And I think that the pattern and cut may be different as well.

I found a site awhile back that has many knit and crochet patterns FREE
http://www.garnstudio.com
Maybe you can find something here that you like :)
Since I don't knit I look more at the crochet ones..
Hope this helps, good luck !!
