I use pieces of wooden dowel rod, cut to whatever length I need, and then use yarn or fine cord to tie several rods together, one over another, using the length of the ribbons as a guide for the spacing. You can use tiny screw-in hooks, one on each end of the top rod, or make a yarn/cord loop to hold the rack up. The clips on bigger rosettes slide right over the dowel rod, and the strings on smaller ribbons can tie on. You can add "levels" as you need them.
I hope that made sense, sorry, no pics.
