An Attempt to Demonstrate
Matching Binding on Quilts
with Sides of Different Colors

1. Here is a Half Square Triangle block, which is standing in for a real quilt that has sides of different colors. Also, here are the binding strips for the different sides. These were cut as for standard double-fold binding.
2. The first (print) binding has been sewn on. Note that at the corners where the two colors meet, the raw edges of the binding are aligned with the raw edges of the quilt. The corner in between has been mitered in the standard method.
3. Fold back the narrow end of the second (solid) binding. Press. Repeat for other end of binding strip.
4. Fold the second binding in half, like you normally do for double-fold binding. Then fold back the narrow end to form a point. This will end up being the miter edge. The yellow dotted line is where the seam line will be.
5. Align the raw edges of the second binding with the edges of the quilt and the point even with the adjacent edge. Sew with a 1/4" seam allowance, as is normally done. Make a standard miter at the next corner. At the final corner, align the point end of the binding just like you did the first point end.
6. Fold the binding strip over the raw edge of the quilt, like you normally do. The tricky part comes at the two-color corners ... I "tucked" the print binding inside the pre-folded miter of the solid binding. I needed to hand whip-stitch the solid miter to the print binding to hold it securely together. I wasn't entirely happy with the result, but perhaps you can improve on this method.
7. The completed "quilt" with binding appropriate to the colors on the sides of the quilt. The bottom left corner isn't too splendiferous and I assume you will do a much better job!
