You are so brave, attempting a DJ quilt. I do think that you would be happier, in the long run, if you practice your needle turn applique and use it for the DJ quilt, which is a showcase for really intricate blocks. Find someone who does really good needle turn and ask them to help you perfect yours. Don't get me wrong, because I have seen many quilts that were gorgeous with raw edge applique, or machine applique. I just don't think I would use those methods on the DJ.
