Here is a link to the new project I am starting - planting a small picture frame with succulents. You can hang them outside, or put flat on a table. Note - this is from the site, I am just starting mine!

A few years ago I made a similar project by planting a moss wreath with succulents. It lived on our shed wall for the summer and was so much fun. You start with small cuttings, and let them root in the frame or wreath. After a few weeks they start to grow and spread.
I keep a collection of succulent plants on my porch, just to make projects or small terrariums with.
