The programs I created and printed on "linen" cardstock for a litte texture. I then punched small holes in the 4 corners and fed rafia ribbon through each. I wove the rafia ribbon through to the back of the fan to secure the program in place. I tucked the little bit of extra ends in between the weaves.
I probably should have just glued them somehow, but whatever...I seem to like the make things as difficult as possible (I think my FI would agree)
