Welcome to the Quilting Board!
The Earth without art is just "Eh".
I used Stonehenge for a scrap quilt - all 2 1/2 x 4 1/2 pieces. I found it to ravel more than usual but then again, I was using a lot of batiks at the time so my tolerance for ravelling might have been low. I just used some scraps in a paper piecing class and it worked well. I think it really depends on how much it will be handled in the quiltmaking and the size of the pieces it will be cut into.
Northcott has some very nice fabrics but like any fabric you must decide if it is what you want to put in your quilt.
I've used Northcott fabrics for years. They are high quality and work well with other brands. You'll be very happy with Northcott. My local Bernina sells their line.
