Brother 270D upper thread breaking
I just got a Brother 270D. After rereading the threading instructions several times, I tried a simple 1 color embroidery project. It was a cotton dish towel with some iron on stabilizer. The machine would embroidery fine for a little bit then the upper thread would break. I finally gave up when the thread broke and there was a birds nest under the last bit of stitching. I was certain I had the right needle, although I did have a lot of trouble reading the size even with a magnifying glass. I used Sulky embroidery thread. Any suggestions as to what I might be doing wrong??
