But you can bind a quilt by machine if you flip things around and do it all backwards. This tutorial will show you how to use traditional bias binding and attach it to your quilt by machine. You need a quilt top, batting, backing, and bias binding for this tutorial.
Step 1: Make your sandwich
Step 2: The dreaded "quilt as desired" and then trim
Step 3: Make/Acquire/Conjure Bias Strip
Step 4: Attach tape to the back of your quilt
When you get to the corner, you do the same fold and turn method that you use for the traditional sew-in-on-the-front method. This gives you a nice mitered corner.
Step 5: Sew along the back 1/4" in from the edge
Step 6: Fold binding around to the front
Step 7: Sew the tape down
Ta-da! Now you've got a *very* securely bound quilt and you didn't have to take a single stitch by hand.
