I have made my own in the past... so chosen my own fabric... it's not hard at all! I've found in the past that some of the funky ones aren't very well made... poor quality elastic etc. My current cover is one that i bought online. It's made by Fitz Like A Glove. Google and I'm sure you will find them. The quality is fantastic and the company is a cottage industry based in rural NSW money goes to people with special needs (who i think even help make the covers). Anyhow... they are plain colours but like i said the quality is the best i have found.
