I've been meaning to write this post for ages. Whether you know what I mean by matched binding or not, as a refresher, I suggest you read
this post. I'll wait . . .
SO, as I said then, matching binding at a 'straight' seam is about 150% times easier than at an angle. I have managed doing it at an angle twice, but both times it was a headache, and I knew I needed to take the time to document the process so I didn't have to waste time re-figuring it out every time I wanted to do it. So finally, this past week, I did just that.
To start, measure around your quilt and jot down how many inches of each color of binding you will need, allowing yourself at least 6-8" extra in length for each section. Then cut strips for each section, and press each in half lengthwise just like you'd usually do for double-fold binding. Lay two colored strips alongside your quilt, about where they will be sewn on. Cut both ends on an angle as shown below. Do take note of the angle you are trying to match. Pictured, mine happens to be a 60-degree angle on my quilt, so I cut the binding at 60-degrees, just in the opposite direction.
Stitch ends with 1/4" seam. Press seam open, then repress binding strip for a nice edge.
Pin the binding to the quilt, with raw edges matching.
Fold binding strip up so you can see how things are lining up. Unpin and adjust as needed.
Now to tackle the next angle. Pin binding to quilt every few inches, smoothing as you go and placing a pin at the next binding color change location.
Turn binding up and using a removable marking pen, make a mark on the side next to the quilt, extending the angle of the line.
Unpin the binding strip, lay a clear ruler over your mark, and draw a line 1/4" away, toward the loose end of the binding. Use your rotary cutter to cut along this longer line. Now you're ready to cut and add the next color as in the first step above. Continue on as your particular project requires! Though it involves some up and down, I find it easiest
to machine-stitch one connection and pin it in place, then measure, cut, and add another color, pin in place, etc., moving around the perimeter of your quilt. Eventually you'll have the entire binding pinned on and you'll just machine-stitch it on. I usually finish my binding with hand-stitching, but if you machine-stitch your binding, it should work the same way.
Good luck and have fun using this technique on just the right quilt!
