I use to use the dining table for cutting large pieces of fabric. I use to quilt on the table also. Now that our oldest Granddaughter has moved out I took the room as my sewing room. I use to have to share my little sewing room with 3 cats. Now I don't. I use to have to put everything away at night so the cats wouldn't get hair all over my stuff.
I love my new room and only use the dining table to sandwich my quilts and cut backings on.
Whatever works for you is what you should do.
