I bought sapphire 875q keeps jamming!!
I bought a Sapphire 875q and pieced a queen size quilt no issues. Then nothing but problems, had it serviced and still doesn’t work for me lasted issue is top thread keeps jamming In The bobbin area. Can some please help. I wish I would have spent another 200 and bought a Juki new. Now my back up brother machine isn’t working either so frustrating.
