Actually I am not sure, I am sure they are bigger than 12", perhaps 15-16"? I would measure but they are at her house and she is at work, sorry.

You could do a round robin around each block, and end up with several quilts. Just quilt as you go.

That is a very good idea. I will let her know. Thanks

My sister said - The squares are 17". Like the idea of QAYG. Will google it to find a good site with instructions and pics or videos. I am so visual those kinds of sites really help.

Please thank all those who shared their thoughts and ideas. Getting anxious to see what I can do with them. Sure am glad I was able to share those squares with you that day! -
I will do my best to get photos when she is done. Thank you for all of your ideas and help.
