I got the suede from Gulf Fabrics it sells for $89/yd. If you look up Alcantara suede you will know why.

Don't do what I did and go to JoAnn Fabrics. That is what I did at first and ended up pulling my panels to re-do them.
Go with something that is UV protected unless you want to do it over again in a year or so, due to fading.
Best I can recommend is the automotive upholstery brands from:
Novasuede - $10 cheaper
Ultrasuede
The adhesive used is 3M Super 90. You can find it at Lowes/Home Depot. Don't go lower than 90
