Here is a small baby doll that I crocheted a hat, scarf and booties to make an outfit using fun fur. I added a small blanket using a leftover skein of variegated yarn. Here are a few photos.
Here is a little baby doll wavy ripple blanket I crocheted. It uses a basic ripple stitch pattern and here is the free blanket pattern directions.
This fits my little 11 inch baby doll but you can just crochet more rows for a longer blanket. Enjoy!
