The first, and most difficult, step to making quilt binding is figuring out how much fabric you need. I am spectacularly bad at this. I search the internet for formulas, I read books, and in the end my method consists of "make way more than you need". I figure that it is better to have too much than too little, and any leftovers can be use to bind placemats.
So to make bias double-fold binding, I usually start with one yard of fabric for a queen size quilt, three-quarters of a yard for a double size quilt, and a half a yard for a twin size quilt. This will give you plenty of binding, and then some. Start by squaring off the edges - this will make every step afterwards a lot easier:
Clean up the bias edge by using your rotary cutter:
Repeat until your fabric is all cut into strips. Shot of parallelogram getting smaller as strips are cut:
Next, join your strips together to make one long piece of binding. I start by laying one strip out on my cutting mat, right side up like this:
Then take a second strip and lay it right side down at a right angle to the first strip like this:
I use the grid on my cutting mat to make sure the strips are at a 90 degree angle. Don't just eyeball it. What your eye thinks is a 90 degree angle just isn't. Measure. Then put a pin in it like this:
Next, draw a sewing line parallel to your pin from corner to corner like this:
It's important to draw the sewing line. Don't just eyeball it, because what your eye thinks is a straight line, ain't. Next, put a second pin parallel to the sewing line like this:
Now sew your two strips together. Sewing your strips this way allows you to sew your seam on the straight grain which is more stable. After sewing, trim the excess so that your seam allowance from your sewing line is a quarter of an inch:
Join all your bias strips together the exact same way until they are all joined. I use an assembly line process and it goes faster when you have done it a few times. After you have all your strips sewn together and the seams pressed, fold your binding horizontally wrong sides together and press:
That's it! There is nothing new or unique about how I make binding; I learned how by reading books and coming up with a method that I use every single time so I can reduce the likehood of mistakes and reduce the frustration factor. (Really important when you are impatient to get a quilt done.) Chris, let me know if something isn't clear or you need help. Miss Eileen, are you reading this???
