Machine Applique: Ideal when a very fine finish is desired. This weight disappears so your fabric is the feature. Use for a straight stitch, small zig zag , Blind hemming stitch , and Blanket stitch. Machine Embroidery: Great results every time. Use 50wt in the bobbin as well, or your regular bobbin thread - in which case tighten the top tension a little. Use a Microtex 80/12 needle. Machine piecing: Gives a great result with a nice flat seam every time. Machine quilting: Use for very detailed machine quilting with a lot of back tracking such as feathers and heavy background quilting . Perfect for quilting that creates texture when you dont necessarily want to see the quilting lines. Use the same thread in the bobbin and a Sharp/Microtex, quilting or even denim needles 80/12. Long arm quilting: Perfect for creating texture where you dont want the thread to be a feature. Backgrounds, stitch in the ditch, basting quilts, whole cloth quilting, micro quilting for dense background designs. Match bobbin thread.
