Lots of what you need to improve is practice. I found a local quilting group when I first started. They were great help in the learning process, and dues were only $24 for the year. Sometimes churches have groups too. I know how you feel about spending that much on classes, but sometimes it is worth it just to splurge on yourself... I am sure that you do not do that often enough..Also remember you should have a completed quilt at the end...
