I use the normal stitch and the same tension if the same cotton on both bobbin and top. But get a piece of sandwiched fabric as if it is the quilt and practice first until you are happy with the way it looks. Put a new needle in too and take your time or big stitches will appear and spoil it. Check the tension to see if both top and bottom are good. Lately I found that I cant use Rasant and Threadart cottons together, it doesn't see properly and I have had to unpick a whole big block, most annoying when you think it is right only to find out it is not. Remember practice, practice, practice. The more you do the better your work. GOOD LUCK. :thumbup:
