Quilter’s Son,
I have no words for your double loss. It is nice to see you are handling it as well as you are.
is there someone that your mom quilted with that could help you figure out what you have? If not perhaps you can find a list of her customers and contact one or two for guidance on where to find the quilters in the area?
I have found that you will be overrun by people that quilt if you do decide to go the estate sale/ yard sale route. Not a bad thing but it can be overwhelming.
The advice you have been given in regards to a guild nearby and all the rest are great if you have the time. An estate sale would probably be the most efficient option for you but as others have said, they really should be knowledgeable about quilting, have a friend or customer of your mom’s meet them with you.
I wish you the best and please post more pictures of her wonderful quilts.
