I have a Brother SQ9050....not a very expensive machine. I've read so many places that if the tension on the straight stitching is good, then the problem with the FMQ isn't tension....that said...talking about thread types. I'm going to go back to my regular C&C thread and see if it works. I've been using a extra large C&C spool and being at the end of the spool the thread gets really curly and 'sticky' so I'm going to start a new spool and see if that makes a difference. This is the type of thread I've been using and haven't had any issues with 'eyelashing'. Then with this particular quilt I want to be as perfect as possible, I read that other threads are very good for this and that. I'm very confused about thread types and weights...but I don't think my machine is liking the special threads like King Tut so I'll try different threads and post results. Babysitting tonight and tomorrow night so I won't be able to do any sewing till Friday. :-(((
