The cutting boards are usually at Walmart or in most Fabric stores. I imagine your Joanne's will carry one (I'm guessing as we don't have a Joanne's here). Do you have to sew the panels together? If so just remember to line up your piping so it flows evenly across...you'll want to check and recheck your measurements so it is going to flow when you are looking at the curtains when hung. Make sure your thread is the correct one for your fabric....something not too light weight wise so your stitching will be nice and even looking. Are you just making a narrow hem on the sides of the panels? Keeping that straight will make the curtains lie nice and flat once hung. Your choice of fabric is inspiring....I have an old heavy chesterfield throw I bought a couple years ago for a dollar at a yard sale....It is a deep rich gold color and although I didn't have any big plans for it I thought it was way too much nice fabric (with contrast fringe) to pass up. You could easily recover dining room chair pads with it. So now I am planning on using it to make a cover for a cushioned window seat I have in my dining room.
