The bed borders are old, old things -- probably made from random glacier rocks turned up in the fields. If I were starting from scratch I'd probably use brick, like I have around some of the newer trees. But I really like cobblestones for edging, so I'm buying a few at a time when I can. The wagonwheel garden has some larger, more upright rocks which is part of what gave me the idea to put the pink mica there.

I'm still not completely sure where I want to put the fossil rock though. It needs to be somewhere I can see it all the time, but out of the way -- and where if it falls over it'll land on soft ground and hopefully not break. But I'll be burying about a third of its height so it should stay put. What works with a megalith should work with a microlith!
