I only use topstitch needles for all forms of sewing. Several different sizes but always a topstitch. For embroidery I use a 40 wt. poly thread on top. I am wondering if you need a heavier thread on top. I use Bottom Line 60 wt. in the bobbin unless I want the top and bottom to be the same. Then I use 40 wt. top and bottom - this is for embroidery. For piecing I use So Fine top and bottom. For quilting it depends on the look I want. Sometimes a 30 wt. like King Tut. If you are having a tension problem I suggest you experiment with several settings using a sample of the quilt you are making. Dont try on your quilt until you get things the way you want.
