For the pattern I used LionBrand's Pattern for their 9-Patch Baby Blanket found here. After finishing the pattern I found that this pattern was WAY too small for a baby, so I added an extra row to each side for a total of 12 patches rather that 9. For the edge I did a simple shell.
Border: Sc in any space on the edge, skip next space, work 5 dc in next space, skip next space, repeat from star around the entire blanket until you get to the first sc. Slip stitch in first sc and finish off. It is ok if you don't have the exact amount of spaces needed. Just kinda fudge it a little. It will look the same.
