I ordered through Zazzle two beautiful pillows: Blue White Chevron Pattern Lumbar Pillow 13 X 21. The order date was June 28. The two pillows were delivered to me on July 8. Now I need one "solid color" square blue pillow 18 X 18 (do you make 18 X 18 size) or a pillow cover from the same "blue" or extremely close to the same blue that is in these two blue/white chevron pillows. Do you have a solid color pillow with this same blue that I can purchase or that you would be willing to make or a pillow cover? Also, what size and price? Thank you so much.
