I am good with the throat space since there is 12 inches and I can get a good 8 inches to quilt and yes you lose apace as you have more finished quilting. My biggest problem is getting the tension correct on the Jazz....I had a Gammill and realize there are limits with these smaller frames. Any suggestion on fixing the tension on the Jazz are greatly appreciated. I am going to try to work these out and finally go back to quilting. Happy threads.
