I have found that a solid, because of its "solidness," really has to go with the prints I'm using, or it sticks out as a miss. The blenders are easier. And also that fabric that you buy and never use isn't so much of a bargain. If you're planning to make a quilt with all solids, then buy some assortments that appeal to you. To blend them in, though, I've discovered that Martha's Quilting Corner will work with your swatches to find a match. They get back to you very quickly, too. They have Moda bella and blenders, Kona, and Kaufmann fusions. Better than dealing with online pictures, which can be very unreliable. I recently bought 13 yards from them and was very pleased. Shipping is exactly what the post office is charging, and they can really cram a lot into an envelope -haha!
No affiliation, etc.
