ok, so my dads birthday is coming up. And I want to make him something extra special.

So this is what I thought up.

I giant cookie, in the shape of a guitar. But not just lay down, I want to stand it up like its in a guitar stand.

Now I was thinking I needed to do it in peices. And I will do electric, cuz of the thickness.
But how do you think I could puill this off? I would really like to use sugar cookie (his fav).

TIA

Find a clipart of your guitar. Print it out the size you want, then trim. Use a good firm cookie recipe, like NFSC. Roll dough 1/2" thick. Use template and handcut shape. Bake in low oven (300F-325F), watching carefully for it to start browning. Let rest on tray for a minute, then remove to cool.
Cut a template for 90 degree triangle piece, one side needs to be tall enough to support guitar, other side needs to be just long enough to stablilize standing guitar. Cut this piece out of dough and cook.
Decorate guitar. Let dry well. Then attach support piece to back, using choc melts or royal icing.

HTH

after decorating and drying, you may need to add support behind the neck. use melts to attach skewers or popcicle sticks to back side.

thanks!

I should be more clear, I want this to be almost life size.... a complete replica of his guitar.

So when he see's it, it looks like his guitar is sitting there on the table

Guess you could use the Xerox at work, and make copies of your Dad's guitar (in sections).

ok!
(PS thanks for fixing the name!)

Im mostly worried about how to stick the pieces together, and make it stable enough to stand.

Could you cut foam core in the guitar shape and use that as a backing. (Just an idea.)

I would start with one whole template. Divide it into managable cookie pieces. But, instead of a straight line to divide the pieces, cut a tongue and groove as in the picture here:

When the cookies come out of the oven, immediately place the template over them and trim any spreading. That way, they'll fit together perfectly.

I would also reinforce the back of the guitar with a strip of foamboard glued on with royal icing.

However you do this, it will be HEAVY. Be sure you have really good support.
