I just had a brainstorm
I had bought a set of shower curtain, hangers, plus ceramic toothbrush holder, cup, and soap dish.
I only bought it because of the ceramic pieces, and had stashed the shower curtain in a drawer.
The pattern is framed palm trees checkerboarded with a palm frond over a square, all on a cream background. The colors are faded khaki and muddy olive green.
It dawned on me that the shower curtain might just cover the recliner.
Not only does it fit, it looks good. One palm frond is behind my head, A palm in a frame is center back, another palm in a frame is center seat.
I even was able to center a couple of framed palms centered on the arms!
The "fabric" is like a stiff organza. It won't wrinkle. The colors seem to fit into the new color scheme.
There's still some tweaking to do. The "fabric" is translucent, so I left the comforter on it, but it sticks out in front. I'll just have to fold that under and pin it up.
I had always thought of sheets and pillowcases as sources of fabric, but I never thought about a shower curtain.
