Thread Heaven

I ordered some Thread Heaven and it arrived today. I haven't used this particular product before, but I have heard good things about it. It is supposed to stop the thread from fraying and tangling. I find fraying is a problem from pulling the thread through such a fine fabric like those used in HAED charts. I will write a review of this product once I get a chance of using it. It is also supposed to be very good for using metallic threads so looking forward to that too.
