Suggestion:
Have a moderator change your subject title to 1/4" seam allowance/setting points (or the professional name for it) and put this post in our tutorial section, please.
I am learning so much as I read it, setting it in my mind for use later. Your photos are so clear. You explained your situation so well when you created the post. The interaction between you and other members is sooooooooo good. The coaching, nurturing and teaching in this post are some of the things the Quiltingboard is about to me.
Your fabrics are pretty, your work is good. Your post is teaching so many people! Thank you for sharing with us. I am hoping you continue to post photos and updates as you walk through this and I am serious about it being in the tutorial section. It will be a helpful tool for many.
