Okay, here's the zip-front cardi I've been working on. Thanks to everyone who helped.
This pattern is one of Paton's free ones (http://www.patonsyarns.com/pattern.php?PID=4966&cps=21191). However, I didn't want the flared sleeves, so I unflared them.
I see from this picture that I have some more blocking to do as the knitting around the zipper isn't very straight, but nonetheless, here's my first 3D knit project (other than a hat).
The sleeves are a tad too long, and I didn't sew them on correctly (I think I used some kind of whip stitch, which isn't what I intended). Oh well!
