Can it be done?
 

Looking for a disappearing 4, 9, or 16 patch quilt pattern. Anything out there?

Here's one for you http://www.favequilts.com/Block-Patt...16-Patch-Block. Have fun.

Thanks. Evidently the rest of my post didn't show up.. I am looking for it to use only 2 colors, of different shades and patterns, but just blue and green. Can this be done?

I would say sure, just use high contrast.

Okay, I'm going for it. Thanks!!

I have seen D9P done in red and white and is quite stunning.

I have seen several D9P in two colors. As Tiggersmom said, use high contrast fabrics like a dark blue and pale green, etc.
