Sure, I'll send you a pattern...
Right now the only thing I have is the actual piece that I bought on ebay. Since I'm a firm believer that any time someone does something for the first time, the result is not the best, I will be working with an upholsterer who does this for a living. I don't know how much he will charge for this type of custom work, but I'm sure it will be insignificant, although IIRC his hourly rate is higher than the minimum wage. Since I'm going to present and exchange ideas about how to make this piece easier to install and use, it's probably going to take a little longer to do. (Not sure how much longer, but I'm figuring I'm safe with no less than fifteen minutes.) When the pattern is all worked out, I think the upholsterer will present me with an invoice. (Yes, I know it's weird to expect to pay someone money, but he's a little strange, and he just won't work for free.)
After the pattern is developed, we'll see what materials work best and how much it will cost. By pooling a larger quantity I think we might be able to get a finished piece done for less $$. Yes, I know you are only asking for the pattern, but I just thought I would mention this. Anyway, when you're ready just, send me the address of where you would want this shipped (at my expense, of course), and I'll get it out to you right away.
Best regards,
