I always have hand work, long arm work and piecing work going. So if one machine is out of commission I turn to one of the other projects. When I had to send my LA back to Texas for some major repairs I did miss it but had the other projects to occupy myself with. I would take this opportunity to try and bond with your other machine. Start an applique project you have been wanting to do or use it for piecing to see if you can't like it just a bit better. Remember things could be worse and you could not have any backup machines at all!
