Mitred Corners Sew-Along

By: Heather S.

Supplies You'll need:

A quilter’s ruler with a 45 degree mark
A marking device, like a chalk liner
Some pins
A sewing machine

Step 1

First, you need to make sure that your fabric is square. Not cut into a square, but that all of the corners are a 90 degree corner.

Then you need to determine your “reveal”. This is the amount that will show on the other side of the project. On the back of the fabric, using a quilter’s ruler, mark the reveal on all sides of the fabric. A chalk liner works great for this.

Step 2

Once that is done, you should have an intersection at all of the corners of the lines you just made. Now its time to use that 45 degree angle mark on the ruler. You need to put the ruler so that the edge lines up on the imaginary line that starts that the very tip of the corner and extends through the intersection of those lines already drawn. You should be able to line up the 45 degree line on the ruler with one of the already drawn lines. Then draw in this line.

Step 3

Finally, you need to mark the stitching line. This line will be perpendicular (or 90 degrees) to the line just drawn. Mark this line as well.

Step 4

There should now be 4 intersecting lines drawn.

Step 5

Now to actually make the corner. Take two straight pins and insert them on the original lines drawn, so that the pin heads hang off the edge. Fold the corner, along the tip of the corner line and match up the pins. Then pin along the stitching line, which was the last one drawn.

Step 7

Now stitch the corner and trip the excess triangle corner at ¼” from the seam. Turn right side out and press.
