I had a small scrap of obsidian that I felt confident enough to tackle the other evening.  It was small to start with and was kind of thick so I didn't think I would be able to do much with it.  My past experience with obsidian was not good in that I hinged and stepped it pretty bad.  I was able to thin it down fairly well (for me) and ended up with a short and wide preform.  Suddenly the thought of making a heart came to mind.  I gave it to my wife and she really liked it.  Then I realized I should have waited two more weeks and saved myself having to come up with a mothers day gift.  No, there is no significance to a Black Heart.  I have some red slag glass and I'm going to try and match it with that.
