Using RKT to form a shopping bag. It will be approximately 6" x 8" x 12" high. I do not have a form that size. Can I form it by hand (will it keep its shape) and then carve the rectangle? Or do I need to create multiple layers and stack them. I'm going to add chocolate to the mix to make it firmer.

In a pinch I have used a cardboard box lined with wax paper. Once it set, it slid right out and i just peeled the wax paper off. HTH!!

That's a great idea. Would it bulge the sides of the cardboard out? I've not used RKT before for cakes. How long might it take to set, given a recipe with little butter and chocolate added?

I used a shoe box and didn't have any issues. See if you can find a heavier cardboard box that is just about the size you need. You can always cut it down some if need be once it is set.
I let mine set overnight....just to be on the safe side.
