Great tips and thanks Everyone!
For ending the serger threads there two different methods we use in class. You can use a dot of fray check.
You can also stitch off and leave a thread tail. Fold that thread tail back down over the seam line (where you just stitched). Turn the fabric so you are stitching over the same threads again. Stitch about 1-2 inches and stitch off on an angle. Don't re-cut the fabric and stitches.
Practice on some scraps first to get the feel of the fabrics and stitches. Enjoy!
