As an aside, we have a selection of shower curtains for succulents that can be used with your new mat. While they can be quite rare, crested succulents don't have to be too expensive so they make a great addition for your succulent collection. I was struck by a crested 'Topsy Turvy’ in Rancho Garcia Nursery’s Etsy store and knew I wanted to add it to mine. Looking Sharp Cactus has many cactus pad options for sale, although she doesn't always ship summer cactus pads.
