I love the second one! I really like the idea of there being a reflection in a pool of water! I think applique may be the way to go with it...I made a quilt for my Sister-In-Law for Christmas that actually reminds me a lot of that picture. It even had camels on it and I never thought of doing something similar!

I've done google searches but for some reason only searched for pyramid quilt and just ended up finding a load of triangle quilts.
I'm wondering if it would look quite good with the black like the one above. I have some more of the graduated colour fabric in blue, which might make a nice background.
