I would make one more dark block to go with the one
and make a wall hanging.

I'd frame them individually and hang them up- they are very beautiful! You could also mix them with some other quilt blocks in a quilt- the other blocks could be pieced or plain. I can picture these three blocks on point down the center of a quilt...

These are all such great ideas!!!

Awesome

How about a long and narrow table runner or wall hanging

Frame them.

They are beautiful. I would either frame them or make a wall hanging. Maybe you could even use them as a bed throw, which would be a little larger than a wall hanging, but it would display your work. Pillows would be ok. They would look nice on the bed or couch, but I just don't think they would have the same visual effect as the other suggestions. Just my opinion. I am looking forward to seeing what you finally decide to do.

You have done such beautiful work on those three. A shame not to make more, but guess the best suggestion I read would be to frame them for the wall. They deserve to be seen.
