If you have difficulty finding upholstery fabric, I do have an old trunk full of remnant fabric you can rummage through.  Alternatively, let me know at least a week before your arrival of your choice of fabric from the suppliers with whom I have an account with so I can ensure the fabric is ordered and delivered in time:
