Welcome to the Quilting Board!
Welcome! I'm in NE PA too. Your quilt looks great!!
Disappearing Nine Patch? Is this a pattern or something you made up? I love your colors!
Love, love, LOVE it! I haven't made a DNP yet, but it's sure on my list!!
There are MANY different tutorials and you can find the links by doing a search on the top of the message board. All kinds of references will come up. I have yet to make one, but am inspired to get going on one! There are so many ways they come out, it's fascinating.
