Looks lovely...I love brights but this looks great. I have never thought of dyeing a whole quilt, but you've proved it can be done with excellent results.
It looks great. I would not have thought of using dye. I have used a light bleach bath to tone down fabrics in the past. I think I will remember the dye for next time.
What a great idea. I actually have a quilt with more white than I care for. I know it won't stay crisp white looking for long. The tan die might be perfect.
