Here's the picture.

On the bottom tier, that decorative silver lining, where can you get that?  Also the middle with the lock and c scroll?

Thank you!

I have the same mold in my shop that's used for the keyhole, I'll send you a link. Do a search for scroll molds and a lot will come up, but a lot of people make their own so you might not be able to find the exact ones she used.
