Yes - all the suggestions are great and all are quite doable but - imho .....you should contact the shop. They should pay for the return shipping and make it right. You have paid good money for their service and they have not delivered. If this is a time sensitive thing then do what you need to do but provide them with pics and demand a some sort of refund on their services. The fact that is is the top thread tells me that whoever ran the machine did not bother to look at the quilt before advancing. I can almost forgive bottom tension issues (I have had these myself and they are easy to miss while the quilt is on the frame) but top tension issues can easily be seen Good luck and sorry they were so careless.
