Aluminum pan make fiesta looking

Hello I might suggest looking at brightly colored table linens. I use serape and other themed thrifted linens for-my entertaining tablescapes.

Hi Gloria, will your aluminum pan be used to cook in after the fiesta baby shower?

If you're not going to eat from it, paint it in festive colors and stencil a design or words on it.

I would go with the table runners going mexican, if you wanted to place non-toxic food safe decorations go to Party City or a mexican display at the dollar store.

You could stencil & paint with Mexican designs.

Here's a neat headboard in that same theme! I'm sure you could use the same technique on a pan: https://www.hometalk.com/diy/paint/furniture/how-to-paint-the-mexican-serape-painted-headboard-37097452

You could pick up some cheap linens at a dollar store and wrap it or get a second pan, paint it and drop the one with food inside the painted one.

If you are going to put food in this pan paint usually isn't food safe. Decorate the table around the pan.

Hello,

As a table decoration, fill with lots of colourful flowers. Lay it on a Mexican table runner, or you could top it off with Mexican hat!

What are you putting in the pan? Maybe you could just get a cute Mexican themed placemat to put it on?

You could paint it and then add lots of flowers

If you're putting food inside, you could get colorful food safe doilies.
