I lost my mother last March, and I got back a lap quilt all in shades of blue (her favorite) that I had made for her. I was using it on my bed, but it wasn't really big enough.
Then I thought about what a great baby blanket it would make for my nephew (who was very close to my mom) when he has his first son (although he's not even married yet).
So, yeah, hang on to them, the time will come when you will know what to do with them!
