I finally finished the curtains for this window behind my tub and I covered the vinyl roller shade and added little ruffle to it. It turned out just how I planned and that does not happen much! This picture is a little blurry though, sorry.
I used a stick from the backyard for the curtain rod and I painted some wooden brackets that I got at a gargage sale for 50 cents to hold the stick. The panels cost me $12.50 and the shade about $25.
I sewed a simple unlined panel then made some skinny ties using the hot glue gun and sewed them to the top/back of the panel. I then just tied them around the stick. I got the fabric on clearance for $4.00/yard and they only had 3 yrds. left, so I cut it in half lengthwise and made "half panels". I didn't want to cover much of the window anyway.
I used spray adhesive to cover the vinyl shade with a lightweight white cotton fabric then I hot glued the ruffle on. The only thing I would do differently is to use fabric glue maybe instead of the spray adhesive because there are still some wrinkles on the shade that have not smoothed out yet.
