Bev I cannot tell you how many people see photos of my semps and ask that...I just assume they look so luscious that people can't imagine not eating them!! (but that's probably all in my little yellow head!)
Serse, there are many many photos/ideas online! Whatever one can do with wire, or wood, one can cover it in succulents
Take your time and make it right! I rushed through my first one, and it wasn't right, luckily I had the time to redo it and didn't loose any plants. I had made it out of wood and it began to come apart within a month
Cheers
