I love making baby sweaters. These are super easy.
Once you start working on them, you will find ways to tweak them and make the style your own.
Try to alternate DC and SC rows, add pretty stitches at the bottom - or flare it out to be ruffled.
It is based off of this free baby sweater pattern - http://www.sandiangels.com/pattern-page.html
And also this free pattern
I used two strands of yarn at once - Baby Bernet in a soft, shiny cream and Bernat Coordinates yarn in "Posy Patch"
I believe I used an "I Sized" hook - but I crochet loosely... so keep that in mind.
You work the body in one section, top down, then crochet on the arms. The sleeves are not made separately then added later. They are worked off the body section. I think this looks much better.
