I have fibro and ruptured discs in my neck,worn out knees-bone on bone so for me a long arm is the only way I can quilt.Sitting on the floor leaning over to pin baste became torture for my body.If I did not go to a long arm my quilting days would be over-sitting at a domestic to quilt was bad for my neck also.I piece at intervals and have to lean back to rest neck and shoulders often.
