I'm a fan of sampler or collage quilts, maybe you can get them to play nicely mixing them in with some neutral fabrics for filler. Or there's always my old standby--potholders LOL.
Since they have such great memories for you it would be a shame not to do something with them. If the ideas above don't appeal, maybe you could frame them or make a fabric scrapbook with each block being its own page.
