Crazy Quilting would be so nice to try as you have many options, you can add pictures, embroidey, add lace, ribbon, etc.
As for the filmsy material, you can also use it to stablize a silk flower on a square, (Crazy Quilting ) of course. You could just do a pictorial quilt using pictures from your wedding. Put all your ideas on paper as they come to you, (so you don't forget), then study it and go from there.
