Any idea how?

My eldest wants a fairy cake and I want to make the wings from something that looks like glass.Using a boiled sweet as stained glass will make them too heavy and I can't get it right that way.

Any ideas as to how to make it from gelatin?

Here is the recipe I have...you can use 1 TBSP unflavored gelatin and 2 1/2 TBSP cool water....mix the water and gelatin and let set for 3-5 min. Microwave about 10-20 seconds until the gelatin is a clear liquid. Paint this liquid onto impression molds (I have plastic sheets with molds of butterflies and flowers)...you can probably make them on vellum...Let dry until the gelatin pops off the molds ...about 4-6 hrs. The gelatin will become a thin crisp sheet that can be cut with small scissors. To paint the dry gelatin use a palette tray and mis small amounts of gin or vodka with either airbrush color or powder color. Use piping gel on the edges of wings and dip into disco dust for accents.........

I use a similar technique in making my gelatin butterflies (see my pix.) The nice thing about them is that you can trim them with scissors to get any shape you want!

Oooh, glad to know. If we don't have a mold, is vellum like parchment or cellophane or is it something totally different?

I don't know if this is what you are looking for but they have a really nice fairy wings that is free at http://www.halloweencostumesale.com havent used it yet but I am hoping you just love these stuff.. Hope this helps.

I just paint the gelatin on a sheet of acetate. When it dries and releases from the sheet, I cut with a pair of scissors and vein with a fine food marker. You can see a dragonfly I made with the gelatin in my photos.
