I recently began a small Penjing project, and want to use moss as a "grass".

I have discovered that I actually have a fair bit of moss in my back yard! But I'm unsure of two things:
1) Is it suitable?
2) How best to harvest it for us in Penjing / Bonsai?

I've read every thread I could find on here about moss, and while I found some useful info about how to propagate or grow moss, I haven't found anything about harvesting it. Especially from a back lawn!
Looking forward to some words of wisdom
