I have actually done it! Use 1/2 starch 1/2 water a large sponge and first put the sponge against the wall (after wringing the sponge out so it doesn't drip), then put the fabric against the wall, use the sponge the saturate the fabric and hold it for a few seconds so it adheres. The beauty of this method is that when you get ready to take the fabric down, just use a wet sponse and the fabric will be easy to remove.
