hard way... use a pencil, ruler and exacto knife
easy way... find a hardcore scrapbooker and they'll have the punches, die-cuts, machines that can cut shapes

once you get that on your viewfinder, you know you're not doing it right... if you see black; your cut-out is too small... if you don't see it but no shape on the bokeh... too big. it must be dead center when you put it on your lens.

i havn't tried the tea-light approach but "ordinary" bokeh from trees that are oof only barely displayed the shape i was using.

do you know the formula to cutout the perfect size for your lens that you're using? i'll tell you anyways... Because the mask must be smaller than your lens' aperture, do some math. If you're going to use a 200mm lens at f/5.6, the aperture will be 35.7mm in diameter (200 divided by 5.6), or roughly 1.4 inches. Thus, your shaperture should be smaller than 1.4 inches. This measurement is true whether you're using a cropped-frame or a full-frame camera. Me I use 50mm f1.4. so my cutout is no bigger than 35.7mm.
