I would like to make a decorated cookie to look like an onion for a bouquet. I have no idea how. Does anyone have suggestions on this?

TIA!

I would look for onion clip art. Use it for the pattern to cut out the cookie shapes and then as a pattern to draw the onion details onto the cookie.

There's actually one in the gallery here by Kneadacookie!

Well, what do you know! There is an onion cookie on here! (and a great one at that!).

I would do the clip art idea and if you onion is white, add a touch of very light blue in some areas for shading. You could also do grey - it just depends on the look you are going for.

ASM actually makes an onion cutter just like that cookie. I saw it in person at Downtown Dough.

Thanks to everyone for your reply! I will have to do a practice batch soon.
