Help needed - pattern suggestion
 

Have just bought on ebay a fat quarter 6 pack of coordinating fabric in beautiful soft colors (Oasis by Moda) . Any suggestion as to a pattern to make good use of them, without having to add much additional fabric? Everything I have either requires a lot more fabric, or utilizes only a couple fat quarters. Thanks.

Are you looking at a wall hanging or small lap quilt? 6 fat quarters is only 1.5 yards of fabric, so unless you do want use addtional yardage, it's going to be on the small side. i would get a coordinating neutral and make pinwheels, using the neutral and one of the colors in each block.

6 FQ's would make a nice-sized Yellow Brick Road. Look in Moda's Bake Shop & you might find some other ideas.

maybe a disappearing 9-patch or 4-patch?

I have that exact same problem. I have quite a few bunches of matching fat quarters...maybe 6 coordinating ones. Not enough fabric for a lap quilt. I think I need to make some pinwheel wallhangings like PaperPrincess suggested.
