Tension issues.....

Arrrgghhh! I had some tension issues last week when doing some sewing for my mystery quilt, but by changing the thread and rethreading everything and cleaning it got better.... for a little bit. Yesterday, nothing I did fixed it. Changed thread, bobbin thread, cleaned it, etc... So I think my Viking has to go in for service. I lugged out the old 'Craft and Sew' machine that has not been used in a couple of years. Cleaned it and then had to figure out where everything was. Took me 5 minutes to find the presser foot up down thing! I got spoiled with my Viking. Did a practice sew and boy does it sound awful! Very clunky and not smooth at all, but the tension is good. So, the delima is..... do I wait for the Viking to get serviced (they are not open until Tuesday and I have no clue how long it will take) or sew my homework on the old machine? It is not due until next Saturday so I have almost 2 weeks to get it done. Thoughts?

On a happier note.... I got some good pictures of Aidan last week outside. He has since come down with a nasty cough and cold that is finally getting better.
