I joined the Yahoo group last week. The previous owner of my PQ1500s belonged and said it was a very informative and supportive site. She was able to download the missing pages for the directions to load a quilt on my quilting frame. I have seen lots of discussion about thread, tension settings, etc. I think it will be very helpful to me when I do finally get everything loaded and running. I happened to think I could probably use any old sheet for top and backing and perhaps a piece of old mattress cover for practice loading and FMQ practice. Does anyone think that would be a problem? I hate to waste good fabric and batting if I have some of these things around.
