Perhaps you should hang it and look at awhile before "redoing" it. It may grow on you. You may want to find some one who appreciates it for what it is. What ever your decision, enjoy the process and honor the spirit of the original creator! Many of the really great quilts have 500-800 hours in them. If you want to redo it, be prepared to spend the time needed and enjoy every minute of it. Don't machine applique it! Make a duplicate if you want to machine applique.
