Hi all, 

I'm trying to achieve this gold look - middle tier. Any tips, tricks or anything to make this easy as possible to accomplish please share!😁

You would have to airbrush the tier in gold. It will give it a clean look like in the picture.

You could also use the canned edible gold sprays or paint it using edible gold luster dust.  Both will require several coats, but it can be done.  If you paint, mixing the dust with lemon extract minimizes streaking.

You could use the Rainbow Dusts paints, too, Those give a really good gold color. I got some and was so impressed with them I opened a wholesale account with them.
