It takes a lonnnnnnnnnnnng time to get good at everything about quilting. Do you have a guild in your area? That helped me more than anything except the qb. Guild is a big help because you can talk with other members who maybe are suffering the same problems as you. Maybe find one who is further along, and she will help you.
One thing I learned on the board that helped me on matching seams was this; lightly bast the seams together before sewing. Then the drops of school glue came along, and haven't had a chance to try it. Looks like a workable alternative to me. Good luck!
