What do you do to pull together an assortment of disparate fabrics to make it a cohesive quilt?

Why — add a fabric that will pull them all together:

Decide what quilt pattern you’re going to make with these loverly fabrics:

(This quilt is courtesy of Pinterest. I apologize to the maker for not knowing her/his name, as I would like to credit them for this wonderful quilt. Please make sure that you know who the maker is when you pin something great. My quilts that are on Pinterest? Not one of them has my name on them, as the designer, maker, nothing.)
Here’s my first block:

Pretty good so far. They are 10 1/2″ blocks, which I will sash. It will make a 25 block, 5×5 quilt.
These fabrics have been hiding out in a white garbage can liner for the last five years.
Why am I making this quilt now ? The answer will become clear soon. I need to find some pictures that I’m hoping didn’t go south with a busted hard drive. 12,000+ pictures became thumbnails (trying not to cry again).
What would you do with fabrics like this? Tell me below. (P.S. There is not an option to just chuck them all ; )

I cut them into 1-1/2 inch pieces and use them as “rats” or “spiders” to start quilting when I’m afraid my machine might eat my quilt block fabric. Saving them, I can piece them together, using them as before, eventually making a 25 patch or 64 patch block. From there, the sky’s the limit. Put black and white (some more black and some more white) fabric around the block to form flying geese to make a subtle star, or sash as is, make a postage stamp quilt (ha!). Because they’re small, it doesn’t matter that they don’t usually play well together. The woman I’m following in this idea is Pat Wheeler of Lockhart, TX . She has some wonderful quilts from these small squares.
I’d love to see a picture of the quilt you’re making, Mary Ann!i love ideas for leftovers in small pieces. I’ve been working on some and always like to see a new idea.
