Thanks homespun. I've just cleaned the bobbin area with extra attention. I also changed my needle once again (I don't buy expensive ones so I don't mind discarding them). I have to press 30 pieces before I can try again with my quilt but I did a small chained sample and it worked ok. I think I've incorporated most of your bits of advice. Obviously, new needle and super clean bobbin/feed dog area. When stitching I am going very slowly and carefully between the 2 squares and I'm also keeping the squares much closer together so there is less time with no fabric under the needle. So far so good.... The proof will be after my pressing. I'll report back. Thanks for all your help!!
