Ok, so as a beginner the mitred corner may seem daunting but it really is very simple. The best way to learn, I’ve found, is by demonstration so I have prepared the following photos of the process. Study them and then read the following and it should, I hope, make sense.
This set of images is purely for turning the corner and getting a mitre. If people are interested I can do a set of photos for joining lengths of binding and finishing too. Let me know.
Remember, this is just one way of doing them that I’ve found works for me. There are other methods out there that you can try and then choose your favourite method.
Sewn with a quarter inch seam throughout.
Sew towards the corner.
Stop a couple of inches before you reach the corner with the needle in the down position.
Fold the loose length of binding to the right (in this image) and finger press a 45 degree fold.
Fold back the length of binding and sew up to this fold.
Stop with the needle in the down position, lift the foot and turn the quilt 45 degrees to align the sewing line with the pressed finger fold which goes out through the corner.
Sew towards the corner, off the edge of the quilt. You may find, as in the above image, the binding moves and shifts the finger press off the edge of the quilt. Don’t worry, the finger press was a guide, you need to judge when to stop and sew off to the corner.
Lift foot, remove quilt and fold the loose binding back over the quilt, aligning the fold with the top edge of the quilt. You can use your line of sewing you have already sewn to butt against which is what gives you the perfect 45 degree.
Place quilt back under the needle and sew from the finger fold down this next side of the quilt.
When you have finished you will be able to turn the binding over the edge and manipulate the mitre into perfect alignment.
