Well Grampz, welcome from NY state! Thank you for your service. I'm sure you're going to enjoy yourself here on QB! Quilting is therapy for probably most of us, as well. Maybe not from PTSD, but from whatever is ailing us.
PP is the unknown for me, so I can't sympathize. However, I love quilting/piecing/binding and enjoying/sharing my love of quilting with others too!
Enjoy your time here and thanks for the suggestion/insight into MI/PTSD.
