I pulled out my linen wardrobe last week for the first string of muggy days in Louisiana. I make most of my pieces and love how soft they feel after several washings. Nothing feels as cool in the summer, even when layered. I was thinking the other day that a linen quilt would feel so cool and soft on hot nights when it's too hot for a cotton quilt with cotton batting. Linen does ravel more, so I would use larger pieces and seams. I would also make sure it has just enough quilting to catch the raw edges of each seam in enough places to prevent raveling out, but not so much that it becomes too compacted to have good airflow. I will need to research battings.
