Well - I've tried everything I can to get the tension fixed on my Singer 15-91. I give up & am taking it into the repair shop tomorrow. I will not be taking it back to the shop that supposedly "serviced" it. The tension has not been right since I got it back. My friend & I took 3 different machines in all at the same time. Just talked to her & she said she is having problems with hers too. So I refuse to waste my breath & time to give them a 2nd go at it. My LQS suggested a shop, so that's where I will be first thing tomorrow morning. I am supposed to be learming to FMQ so I can finish some quilts that are gifts! Gotta get things moving & done!
