where can I get some frabic to put over the frames of acoustic panels..
prefer if there are some colors to choose from and not too expensive.

Muslin linen or burlap are all good options. Tee shirt material would work fine. So would speaker cloth.

Go to a fabric store like Jo-Ann Fabrics.

I'm sure there's a store locator in the link.

Make sure you can breathe through the fabric.

A little resistance is okay for sound panels but it would not be okay for speaker grills.
