I shared how to make your own sandwich binding in this tutorial and here's how I attach it. This is my favorite method for binding only because it's the quickest. It doesn't matter how patient I am stitching my blocks together and then quilting it all, once I get to the binding I want to be done so I can throw it in the washing maching to get that broken in look.
1. Fold open your binding and place the wider side under your quilt edge anywhere except near a corner. 2. Fold the narrower top half on top and pin through the bottom half, making sure the edges are aligned by feeling with your fingers. 3. Stitch all the way to the corner and backstitch making sure you go slowly and check that you're still stitching through both the top and bottom. Trim threads and take quilt out from under your needle. 4. Fold open your binding and turn it so that the back corner is tucked in the wider back side.
5. This is how your back corner should look. Fold the front over like a sandwich and pin things in place. Start stitching in that corner and make your way down to the next one, checking regularly to see that you're stitching through the back side. Stitch until you get about 5" from where you started. 6. Once you get to where you started, trim your binding so that it overlaps about 3" in a V-shape pointing down. Then trim off the inside flaps about 1/4" from the end of the V-shape. Fold the back side of the V-shape in about 1/4" and then the front side in about 1/4" as shown. Iron to make it easier. Carefully fold it over the beginning of your binding and pin. Place it back under your needle and resume stitching. Backstitch where the two ends meet. 7. Use a needle and thread and do an invisible stitch to secure the V-shape. You're done!
I'm pretty sure this won't be the last quilt I make before this baby gets here. I need to take advantage of this nesting instinct! Full log cabin quilt tutorial details coming soon.
