Do you love a scrappy binding. I do for lots of reasons. I like that while I’m sewing it on it changes color. For some reason that makes binding the quilt go faster for me. And I love how it looks. It just add so much to a quilt. Now I know that a scrappy binding does not work for every quilt, but for those times that is does, this is how I do it.
First I cut strips. I like to vary my strips. These strips vary in width from 4 1/2″ to 6 1/2″. They are about 22″ long. This will give you enough binding for a twin size quilt. Then I arrange them in a pleasing manner and sew them together.
Then I use my ruler to cut my strips at a 45 degree angle. Then I take the bottom piece of my 45^ cut bring it over the top of my top piece until the two long edges line up and make a continuation of my strips of fabric. Sew these together. It will form a trapezoid. Is that clear as mud? Then I line up the bias side on my mat along one of the inch lines, this makes sure I keep things straight. Then I start cutting my strips. I like to make mine 2 1/4″ Continue cutting your strips across your trapezoid. Moving the fabric as needed making sure you keep it straight. I just stack my strips on top of each other so I can sew them back together in the same order I cut them. Take these strips to your sewing machine.
Place the bottom of your top strip on the top of your next strip with right sides together. Off set the points by 1/4″ as shown. And sew. (did you notice I had to pice my orange strip) Continue this process through your pile of strips. Press seams. Next fold in half and iron the length of your strip.Then fold your bias binding accordion style and secure with rubber band. Folding it this way verses rolling it keeps it from twisting when you are applying it to your quilt.
