I'll take picture to share with you all!

I'm excited! Small town, we don't get many quilt shows.

Is there any copyright rules about sharing pics of quilts that I didn't make myself?

Have a great time!

Ask at the quilt show. There are rules at many (most major) quilt shows. Some let you photo for your viewing only. We won't know their rules but the organizers of the quilt show will know. If they have a web site they probably have their rules posted.
Enjoy, hope they will let you share with us.
