The silk batting feels amazing and I am sure it will stitch the same as the wool batting that I have tried before. The only problem that I have found with wool batting is that the quilting thread has a higher tensile strength than it, so all of the pressure when you pull up the quilt is placed on the thread. On occasion you can actually hear the threads breaking. Sleeping under wool though is worth it as it really does keep you warm.
I did a fun exercise to see the different weights of the three battings that I have. The heaviest was the cotton which weighed 1.260 kg, the wool was next at 880 grams and then the silk which was 830 grams.
I am still mulling over what I will be doing for my next large quilt.
I do think I will be using the silk batting and it will probably be an appliquéd quilt. I think the two would go together.
Hope everyone has an amazing day!
