Moreland, your work is fabulous!! I just love it.
Ian______, I keep an old paint roller back wrapped with masking tape to roll over my sewing area. It picks up all the stray threads and moves or picks up the pins so I can see them. Your kittens are so young, you'll find a way to train them to enjoy and play with the threads but not eat them. It will take time.
Happy Quilting to both of you,
Sharon
