I stole this idea from pinterest, had to try it out! Heres how I did it!
Next hem all of the edges of your fabric. Then lay it out, and glue the top of the blind onto the top of the fabric.
I started to put some of the slats back in I spaced them every 9 in". Then I ran the string back through the slats as well, and glued them down.
And the finished product! I would make sure to use a little thicker fabric because you do see the slats when the sun comes through.
