This pattern has captured my attention 3 times now. The first two times I knit it on the midgauge.

This time I converted it to the standard gauge machine. (Yes, lazy. It's squished under the lid of my scanner.) I used cotton and made a size larger than I wanted the finished size to be. Then I threw it in the washer and dryer so that it would do all its shrinking before I give it away. The cotton turned out so soft, I'm really pleased with it. And the variegated blues look kind of like jeans. Boyish, anyway.
You can find the pattern here: http://www.allaboutyou.com/craft/Knitting-pattern-ribbed-baby-jacket/v1 The baby model is so adorable. But there are a couple of things I don't like about the pattern. The bottom curls like crazy with no edge treatment and the sleeves do as well. So, I added the 2 x 2 ribbings and I think it's a big improvement. Besides, when the baby grows, the sleeve cuffs can be shortened and then rolled down.
A friend and I worked on this together, did a schematic and adapted it. Here's what the schematic looks like for 12 months. If you'd want a different size or different gauge, first download the pattern from the website and then use the measurements to come up with your own stitches and rows.
Yes, she's getting obsessed with baby stuff....
