I've used this sweater pattern for several baby boys and girls and it's so much fun. This one is my absolute favorite, I made it for my cousins baby and I don't know that she ever used it. I wished it would have fit my littlest man or I'd have kept it for him! I love the colors and it just looks so cute. For this sweater I copied the look of a paid pattern tulips from DIC and added the garter stitch bumps at each color change. I like the seed stitch button band of the super stripes so I kept that.
Here's a few other sweaters I've knit using the free pattern. I can't find the pink and blue ones out of my 18,546 pictures on my drive- sorry! =)
