I couldn't remember the name with the tutorial, it was Charismah's tutorial I used! I wrote down notes to take to the cutting mat.
Yes, I have matching thread for the flange.
My game plan: trim the quilt 1/4" from the edge of the quilt top, sew raw edges(binding and backing) together on the back side with 1/4"in seam, flip over and SITD between binding and flange. Sound right?
