All you need is some cheap mini blinds, fabric and glue. I followed this tutorial here.
They were super easy to make and cost about $6 per shade to make thanks to some cheap fabric is purchased this summer.
The fabric is home decor weight so it is a little thicker then your regular cotton fabric. It shows the light through a little bit, but its not too bad. Eventually I plan on adding some fabric to the back so you don’t see the backside of the blinds. It kind of bothers me seeing unfinished edges, but not enough to have paid $20 plus dollars for a kit to sew my own.
It is such a cheap way to make your own roman shades.
