I happened upon this tutorial the other day, and decided to try it out. I actually found Lazy Cozy's tutorial to be lacking in some aspects: she does not mention that you absolutely need a dropcloth, otherwise glue will get all over your floor! The fabric will also fray if you don't hem the sides. There was no instruction on what to do with the fabric that meets the end of the shade. My tutorial will expand on hers.
I could not locate her adhesive since she is located in the UK, so I used Sobo, the glue I use for all my modeling projects. It did not leak through my fantastic fabric from Jessica Hogarth, but it did leave blotches on the ENJE fabric. I took pictures of my rollers' current state, but I'm going to buy a dark canvas to cover the backs, because we want total room-darkening.
I found that doing the second shade went a LOT quicker after I figured out what I was doing. The first one probably took me 5 hours. I hand-sewed since I don't own a sewing machine, and I have no idea how to operate one. If you use one, I bet you could finish one shade in under an hour.
Read the tutorial with images after the break.
