Perhaps there's a local store with classroom space that would allow you to spend the day sewing on their machine when they aren't doing a class. In my shop we allowed this occasionally and I did it in the LQS here in VA when I was visiting from TX.
If you don't have many of your own projects, maybe you could offer to make a sample quilt top for them as return favor. Or, maybe they even know someone who'd be willing to rent a machine to you; there are quilters allover the world who collect more machines than they can ever hope to use!
