Notes from the pattern page:

"Since the debut of our Learn to Knit Kit, we've had an overwhelming number of requests for an easy baby sweater. Well, this is it! This sweater is designed for even a rank newbie knitter, and in worsted weight yarn it will knit quickly. It is knit in all garter stitch (so all you need to know how to do is the knit stitch) and all in one piece, so there's minimal seaming to do. This is the sweater I find myself grabbing first when we're headed out the door for a day of errands, because it's roomy and easy to get on and off even the most squirmy of babies. With sizes from preemie/newborn to 5T, you can keep all the wee ones in your house warm and cozy. Shown below in our variegated cotton yarn, with the hat pattern that's in our Learn to Knit Kit."
