I have designed and printed fabric from Spoonflower. Twice actually. The first time, I didn't pay attention to the size of the graphic somewhere and the seahorses were about a foot tall in a repeated design. The color was fabulous, I was just wanting smaller ones. I don't have a picture of the quilt I made because my friend loved it, so it's hers now.
The second time, I was more pleased with my fabric. I uploaded coloring pages that I scanned into my computer. The detail is amazing. It wasn't cheap, so I choose wisely when printing yardage.
I ordered the swatches, 6 x 8" for 5 dollars to make a quilt from each daughters childhood art pictures. Vibrant!
