So very, very sorry for your loss. Yes, there are a lot of patterns that I have seen made out of men's shirts. This may be hard for you in the beginning to cut up his shirts. My suggestion would be to fold them up and put away for awhile until you are ready to do a project with them. That is such a lovely idea to make quilts for your children and grandchildren and I hope you keep one for yourself then when you want a hug from him you can just wrap a quilt made out of his shirts around your shoulders and feel comfort. I am sure your family members would treasure these items too. Good luck and please take care of yourself first.
