Hi,Carol,
The pattern I'm using is called Bubbles Baby Blanket by Deneen St. Amour. It is on Crochet Pattern Central. If you can't find it, let me know & I will write it out for you here. It is a simple pattern with a foundation row & a 2nd row that is repeated. It can be made in size you wish by chain multiples of 3 plus 2. Let me know if you can't find it on Crochet Patterns Central.
Hugs, Jane
