It's beautiful! I would do a simple trapunto outline, using a fluffier batting for effect. It would be easy to do and make a lovely throw or, well, whatever size it is it will work. Let us know what you decide and send a picture.

I would cut the panels in half, vertically and horizontally. Then add strips of coordinating fabrics to two sides of each piece to make log cabin variation blocks.

I like the stack and whack idea. Also, if you need a quick comforter for a gift, you could measure off what is needed for the size bed and quickly have a really pretty comforter.
I am envious of aving20 yds!
Have fun with it.

Do you have enough to cut each block into fourths and rotate them around (as if you were doing a disappearing four patch block)? You could also make each block into potholders, hot pads, table toppers, or a table runner if you left them in a row. How about using them in a border around a skirt, or a tablecloth. It's beautiful fabric. Is it cotton? Is it wide enough to use as a tablecloth as it is? How about alternating these blocks with pieced blocks in a quilt? Wow, I just saw that you got 20 yards. That's enough to make something nice, and sell some. I'm nosy--do you mind me asking what you paid for it?
