The basic steps for layering it are:
Rocks for drainage
Charcoal for filtering (I bought it at a pet store)
Plants - small scale, succulents or sedum
live moss (for indoor terrariums - i found mine in my yard)
Pretty Rocks for decoration
Here they are finished~
Susan's - I love the color in hers~
I have a good view from the kitchen sink and I'm amazed how much time they are spending at the feeder. Sometimes they just sit a spell.
Have a wonderful Memorial Weekend!
