I'm always mystified when I see a "for sale" ad (here or elsewhere) stating that the animals aren't allowed in the sewing room. How do you keep them out?
If I tried to keep my cats out of the room, I'd hear nothing but wailing and scratching! They have the full run of the room and often try to help.
My avatar likes to supervise my ironing and help the thread move off the spool as I sew. She likes to squeeze under the closed cabinet and make sure the foot control is OK. My other cat just likes to lay on the chair.
