Here is a site I found "www.spoonflower.com". They have fabric, wallpaper and others.

Hobby Lobby did have some Elvis fabric

I have a very pretty 4.5-5 yard piece of bright aqua fabric that does not show his face, but has his autograph in a darker aqua. The autographs are about 1.5” and the palm trees are about .75”. The photo shows very washed out color but you can get an idea of the print. You may have it for the postage if you are interested.

Don't know anything about these shops, but here are 2 that have Elvis:
