I made one years ago, I used cheater panels sewn togther, looked like a pieced quilt from a distance. I used a light weight batting & cotton batting, made eyelet button holes for the shower rings, also hung it with plastic shower liner. I thought it looked great, visitors complimented it. Had to replace the liner a couple of times due to mildew but the quilted curtain did well.
When we moved it didn't go well with bathrooms in new house so I just sewed up on the sides, added strap handles and still use it as a carrier for Stitch Camp portable table & cutting mat.
