I do use some of the Montessori method, but I found it difficult to use much of the Montessori equiptment because:
1) it is expensive!
2) My children used the equipment for such short time, they don't need many repetitions. It takes me longer to make or find it than it does for them to use it.
I'm still trying to figure out the solution, but I have found asking on the Monti forums less than helpful, because they either think I'm making it up or I get a lecture about them needing the repetitions to get it.

So we try to Montessori-Unschool. It seems to be ok so far!
I use the free online albums a bit - for what I do it isn't worth buying them.
