Covering A Kitchen Chair

Hi All,
I am having my kitchen chair seats covered and also back pillows.Most of the fabrics I find seem to be cotton sateen or quilting fabric.I would like something a little heavier.

I am looking for coral (or possibly teal) with a pattern such as Moorish Trellis,Ogee or other large geometric designs.Does anyone know a reasonably priced place to purchase these?

Thanks,Lynn
