Here’s the second part of the binding tutorial – how to attach binding by machine. You can find the first part here.
There are a few ways to do this, but I find this the easiest way because it involves barely any pinning.
First off, when you attach your binding by machine, you will always have an extra visible line of stitching that you don’t have when binding by hand. You can see this in the picture below, there is a stitching line running along the top binding strip.
Determine which side of your quilt you want that line to be one, because that will be the side you start with. So if you want that line to show up on the back, you start attaching the binding on the back of the quilt.
Pick one of the long sides of your quilt and line up the raw edges of the binding strip with the raw edges of the quilt, just on that side. You can hold it in place with a few pins or clips. Start sewing about 10″ from the beginning of the binding strip and sew a 1/4″ from the raw edges, backstitching at the start. You want to leave the 10″ loose because you will have to join the strips at the end, when you get back around to where you started. Start sewing and head towards the first corner.
Once you get to the corner, stop 1/4″ before the edge with the needled down in the fabric, lift the presser foot and turn the quilt so you sew towards the corner. Drop the foot again and stitch diagonally into the corner, then cut your thread. You can backstitch here, too, if you like.
Now fold up the loose end of the strip at a right angle, then fold it back down so the raw edge lines up with the next edge of the quilt and you have a little folded triangle underneath.
Run your fingernail along the fold in the corner to give yourself a crease mark for where to start sewing again.
Sew along the next edge, starting 1/4″ from the top edge of the quilt (your fingernail crease will be roughly 1/4″ from the edge). Backstitch at the beginning, then sew along to the next corner and repeat these steps. Stop sewing 10″ – 20″ away from where you started and backstitch. You’ll need more room if you have a big quilt, and can do with less on a smaller quilt.
Put your quilt on your cutting surface, binding side facing you. You’ll have your two loose ends with an open section in between them. Please excuse the different fabrics, I had to retake these pictures with a different quilt thanks to having some lighting issues the first time around.
Cut the right strip off so it reaches just a bit more than halfway across the open space. Use a ruler and line it up so you are measuring 2 1/2″ from the edge of that strip. I use a 2 1/2″ wide ruler, which makes this a bit easier, but any ruler will do as long as you can measure an accurate 2 1/2″.
Now fold your left strip end over top of the ruler and cut it off so it overlaps the strip below by 2 1/2″.
Open both strips and put them right sides together the same way you did when making the binding strip. Being right-handed, I open the left strip and lay it horizontal with the right side facing up. Then I take the right strip and fold and smoosh the quilt a bit underneath so I can put that right strip perpendicular to the left one (with the cut end up and the attached end down towards me), wrong side up. Pin the strips together and draw a diagonal line as shown. Again, this is exactly the same method you used to sew binding strips together, just a bit more smooshed. The more room you leave here between your starting and stopping point when attaching the binding, the easier it is to maneuver the strips and quilt around.
Sew on the diagonal line.
This is what it should look like. Again, you’ll want to be able to cut off that top righthand triangle, so make sure the diagonal seam goes the right way. Open up the strip and check that it does before cutting it off.
Trim the fabric to 1/4″ from the seam.
Open it up, finger press (or use the iron) the seam open and check that it all lays flat. Finish attaching the binding on this side.
Now that you have the binding attached on one side, press it outwards for a nice, crisp edge, and pull it over the corners.
Fold the binding over to the other side of the quilt and hold it in place with pins or clips. Fold it fairly loosely, you don’t want to pull too hard. It just has to cover the stitching line from where you attached it to the first side and extend beyond it by a couple of millimeters.
Using your walking foot, place the binding under your foot so that the needle hits it about 1-2 mm from the edge of the binding. I like to move my needle over as far as it goes so that my walking foot still has the entire binding underneath it and moves it nice and evenly. And it just so happens that I can align the walking foot to the edge of the quilt on the right and move the needle as far to the left as it goes and it works perfectly.
You also want to make sure your stitching is further towards the center of the quilt than the first line of stitching so you a) cover that line, and b) don’t end up stitching through into the binding on the other side. You want to make sure you’re stitching beside it, but as close to the edge of the binding strip as possible so you don’t have a flap there.
When you get to a corner, stop about 4″ away and leave the needle down. Fold your edge in as shown and pin or hold in place with clips. Pushing the fold right down with a stiletto or other pointy implement will help to make sure your corner aligns properly.
Use plenty of pins or clips in the corners, and use your stiletto to hold things in place when you have to remove the clips and your fingers get too close to the needle.
Continue stitching until you get to the corner, then stitch out towards the point, back again towards the center of the quilt, and then keep going along the next side. This closes the opening that would otherwise be there under the fold.
Keep going all the way around and backstitch at the end to secure your threads.
And there you have it! You should now have a tidy little stitching line on the other side of your quilt that hopefully didn’t hit the binding anywhere, and a securely folded over binding without any extra flap.
