I kind of invented a technique for this, bunching and tacking applied fabric to get texture (and, in the case of the rainbow chiffon sky, color). (Others may have invented it before me, but I haven’t seen it.)
I did some post-processing, too; the colors came out a little too similar, so I used Sharpie markers to alter and define, then said, “What the heck,” and went in with watered down paint to create more subtle variations. That lets this work with another song, too; I used violet paint on the peak, so it has “purple mountains majesty”.
The ones I did last year were all sized to fit the christmas tree, so I can enjoy them every year. We had several in our camper, but kept them when we sold it.
This one wound up on the kitchen wall.
We expect to move in the next year or so; I’ll get rid of lots of decor in the process. Maybe I’ll create a collection wall in the new house.
But I seem to be rather nomadic, moving every few years, and a bunch of small pieces can be reconfigured to hang on any wall.
My husband brought home a king-size bed cover that he wanted to display; there’s only one wall to fit it. It’s ugly, but I moved everything off that wall so we could hang it. I hope he doesn’t want to take it to the next house. Maybe it could get lost or damaged…bwah ha ha ha.
ETA, in many cases, I have 3D printed a frame that is an integral part of the piece (mostly state outlines).
I knew hubby had a LC account, but I didn’t realize he checked it out much.
But of course he saw my comment that his bed cover was ugly. He’s being a good sport about it.
Congratulations! Your scraptastic project is one of this week’s Featured Projects! 
so clever!
