Finally! I made a baby blanket, gave it to my sister, and now I can talk about it.
I chose the Colorful Circles pattern from Baby Afghans.
Rather than crochet the multicolored version, I decided to use gray and yellow yarn to match my nephew's nursery, and decided I'd give it to her at a shower her friends threw for her because the theme was--what else?--gray and yellow!
I used less than one skein (268 yards) of Loops & Threads Impeccable Solids for the circles, and then about a skein and a half of the gray. I didn't think to work a gauge swatch, but I did play around with the squares for a while beforehand until I decided I needed an I hook for the circles and squares to look 'right.'
I love this little afghan. And I loved making it. It would make a great weekend project, or it could be crocheted up in a few evenings. I love these little sunshiney circles in the blanket. I love knowing that my sister likes this blanket because my family is the BEST about receiving yarncraft gifts.
