I want to do a basketweave cake with Hershey's hugs (a basket of hugs) and wanted to make the basket the colors of the Hugs wrapper.

You can airbursh it with Silver paint.

yup airbrush is the way to go. If you dont have an airbrush, you can get a spraybottle, mix your luster dust and everclear and use the spraybottle instead, you usually have to use a pin to keep the nozzle clear but it will work.

You can color the BC a light gray color and then spray it with Duff's silver color spray. I found this @ Micheal's and it comes in a small spray can. I have used it on gray fondant and it gives a really nice silver color. Good Luck!!
