Here's a close-up of the finished attachment. I have an 1 1/4" hem with one hem line at 1/4" and the other at 1" - I pulled the threads from the glide bracket to the inside and knotted them where they met the hem lines.
If I can find a nice print, I'm going to make a double-layer curtain (stitched wrong sided together and turned) so there's no corners to mitre. Then I'm going to cut 1" circles around the glide brackets so there aren't any sharp corners, then I'm going to use velcro to attach the glide bracket to the curtain (scratchy-side on the bracket, soft side on the curtain) so I can easily take them off for washing.
