I’ve wanted to make one of these for a while. I didn’t have any starch or fabric stiffener on hand, so I used a bottle of Elmer’s. It worked pretty nicely.
Those are the general steps I took. A few hours after #4, I applied some more glue. I suppose one could pour the glue in a bowl and dip the doily in it beforehand to completely saturate it without re-applying later.
