Howdy & welcome to the boards from Texas. So sorry to hear of the loss of your dear dog. They become so much a family member & it's so hard to let them go. Try to remember all the good times you had with her while she was with you.
I still crawl on the floor to sandwich my quilts but have been known to take them to the local Senior Center & borrow some of their big tables. Just last year a sewing lounge opened up in our town & they have big tables that I will be able to use also.
Hope you enjoy the Quilting Board. There are lots of helpful people here to are willing to share their knowledge with you.
