Please note: this is not a comprehensive tutorial for creating and adding binding to a quilt. There are many wonderful online tutorials that cover all details for making binding (my favorite is here.) These are simply the steps I use to add binding specifically to my Christmas Tree Skirt.
1) Create your binding. For this project, bias binding is recommended, but a straight-grain binding will work fine.
2) Begin attaching binding, starting on one of the outside edges of the tree skirt. When you come near the first point on the skirt, stop sewing 1/4" before you get to the seam line. Back stitch and remove tree skirt from machine.
3) Fold binding strip back so that it is in line with the raw edge of the next section you will be sewing. The fold on the binding strip should align with the seam on the skirt:
4) Fold the binding strip back on itself, lining up the raw edge of the skirt with the raw edge of the binding strip:
5) Starting at the edge of the fold, back stitch a bit and then begin stitching the next section of binding.
Repeat steps 2 through 5 for each of the outside points of the tree skirt.
6) When you get to one of the points at the tree skirt opening, stop sewing 1/4" from the point. Fold binding strip back so that it is in line with the raw edge of the next section you will be sewing.
7) Fold the binding strip back on itself, lining up the raw edge of the skirt with the raw edge of the binding strip:
8) Starting at the edge of the fold and back stitching a bit, begin stitching the next section of binding.
9) The center opening of the tree skirt is the trickiest part because of the concave angles and the small space in which to work. When you get to a point, stop sewing right at the point. Leave the needle down and raise the presser foot. This will help with the pivot. Rotate tree skirt so that your next part is lined up:
10) Leaving the needle down and the presser foot up, pull the binding strip around so that it lines up with the raw edge of the next section of tree skirt. The binding behind the presser foot may bunch up a little, but don't worry about that. Just make sure that the binding ahead of you lies flat and is lined up with the raw edge of the skirt:
11) Lower presser foot and begin sewing next section. Repeat at each concave point in the tree skirt center opening.
12) When you get back to your starting point, join ends of the binding. Now that your binding is attached to the front of the tree skirt, I recommend that you hand stitch it to the back. Machine stitching it is possible, but might prove to be challenging around some of those concave points in the center opening.
