Before I show you the after, let's have one more look at the before.
First I spread the fabric out face down and rolled the shade just beyond the desired length. Then I trimmed the fabric about 1/2" wider and 1" longer than the shade. **Note the shade is actually longer than I needed so I only covered the length that would show if the shade was closed on the window.
When the time came to glue the fabric to the shade, I could not locate the fabric glue so I used a glue gun loaded with fabric glue sticks instead.
My shades have to be rolled up manually and no longer have the pull release feature that sometimes works - sometimes doesn't with roller shades. This is OK with me though because they will never be pulled down.
When I tried to roll the blinds up and down previously, I had not correctly installed the brackets. They do officially work. Sorry for the confusion.
Did you notice any others changes? To keep this post from being too long, I will share them tomorrow.
****Revised to say***
Read comments below. Fabric that is too heavy may not work for this project.
