I stuck with the arrangement motto that you need a "thriller, filler and a spiller".
Pick a well draining bowl or container.
Fill it with cactus mix soil.
Then start adding the plants.
I started by already having a plan laid out in mind. I like to use the tallest plant in the center for my "thriller", then do my "fillers" opposite each other based on color and leaf shape. Then I went back with the "spillers" and put them on the outer edge so they would grow out and hang down.
Then I went back and added a few pebbles to provide extra support and cover any bare spots.
I think it turned out beautifully. Hopefully they will be happy outside all summer (Lord knows we never get much rain anyways) and this fall I'll bring it inside to live as a houseplant.
