I saw that commercial too....it was a "quick" shot, but it was a grandmothers fan.
Bree...if you make the wedge out of 2 1/2" strips they will be very narrow. They are a tapered wedge and widest part is top.....its been awhile since I did one, but I think mine were wider than 2 1/2". There is an inexpensive template available...used to be at JAF....a good one to have...
do you hand applique or machine?
