There was a whole series of decorative outdoor pillows with similar cactus designs on them, and the original art was done by the same person.  We bought all 4 designs that were available, and duplicated one of them, because we needed a fifth pillow.  The colors are vibrant, and they coordinate beautifully with the patio seating set and outdoor rug we also purchased from Wayfair. 

I have recommended this series to friends, but was told that they were out of stock.  Lucky I caught them before they were gone!
