Evidently someone had made these necklaces for all the moms in the pack long before we ever got here from an idea they'd seen before. (I did some digging, and this is the only place I could find that sells them -- starting around $7.00/each.) I can't bear to spend that kind of money on things that I can clearly make myself, so here is my tutorial as I make one for myself.
7/8 inch (22mm) wide Centennial Blue
5. Pin the fronts together matching up the angles and making sure that red ribbon will lay flat on green ribbon, since you haven't sewn them yet. Remember to again switch your threads to match the red and green ribbons.
Here are pictures of the back portion, with the underneath side showing the reinforcing square.
Here is the front, showing how they line up on both sides. You can see that my stitching continues on all 3 sides of the red as I work my way back to the top (neck) portion.
The finished product! I am very happy with how it turned out. I think it took me about 20 minutes to finish. Well worth my time and money.
