Your quilt is lovely. Your points match so well, so you are doing a lot of things correctly. Once you move your connecting to a straight edge, you will be fine. Some times we hit a problem that discourages us so much we question our abilities and want to give up. Please don't let that happen because you are doing so well. Once this is mastered, you will really enjoy your quilting. The quilters on this board are fantastic and so knowledgable as well as willing to share their skills.
