Hi, Susi -
I'm new here. I'm actually going to make a blanket for my stepdaughter's bed. She has a full size bed and I am planning to make one to cover the top of her bed (not down the sides).
Here's a very simple pattern -
Crochet hook Size N
Yarn - Lion Brand Homespun (any color you choose)
Approximately 8 skeins for a full size bed top
Ch 100 sts. (measure this chain across the end of the bed - is it long enough - too long? Make more chains or shorten as necessary)
Row 1 - Hdc (half double crochet) in 3rd stitch from the hook, Hdc in each ch across. Turn
Row 2 - ch 2 (hdc), hdc in each st across. Turn
Repeat Row 2 until the blanket is the desired length.
