I had quite a bit yarn of the Plymouth Encore Yarn left over from my Bohemian Jacket so I decided to make a friend of mines little one a sweater. Encore is a perfect yarn for babies and kids because it's warm and most importantly washable. Encore also has so many color choices. My interest in freeform crochet inspired me to make a spiral motif for the back.
I used the instructions I found here to make the spiral. I did tweak the increass a bit to prevent wavyness. After I got it to a size that seemed about right I added dc, tr, and dtrs to make it more square. After that I felt it needed a bit more length and added some to the bottom of the back.
I took a look at some of my old patterns to see how big the sleeves and fronts should be for a toddler size sweater. I used fpdc, dc alternating for the sleeves and front. I think it would be fun to add small spiral pockets to the front as well.
It was a bit big for her son at 6 months but worked with the sleeves rolled up. It fits him well now at one year. I want to make another one soon and write up the pattern. I'm not sure if I will make it free or to sell though. The trick will be to make it in enough sizes and that's a new thing for me.
