You can do the 3D pinwheel, without cutting. I made mine with 5 1/2 so 61/2 would be great. I got the tutorial on here a few yrs ago and its so easy.

I used a bunch I had to do the exploding block and was super happy with the results. Additionally, I agree with the other member who suggested charm square patterns.

You could make snowball blocks with them.

Make a chevron quilt using them for HSTs.

Any charm square pattern will work, your quilt will just come out bigger. I agree with making Falling Charms, nice pattern ...

I have used them to make half square triangles that were light and dark. Loved the larger squares. I made a large throw the is my go to quilt for snuggling.

Well I guess it all depends on what you want to use the quilt for. You could use thin sashing in between each block and then use one of those permanent pens and write your favorite quotes, sayings, bible verses. Or if you are a reader like me write the title of the books you have read. Then it could become your curl up and read quilt. Sorry if it sounds crazy. I'm just simple like that.

My first thought was a snowball block. Find a good fabric that will contrast with your fabrics. Cut that contrasting fabric in squares. You decide the size. Place them in each corner and sew them on an angle. Like half a flying goose.When you sew the blocks together your pretty fabric will be intact but you will have cute little squares through out the quilt.
