I use a lot of bias tape in the construction of my aprons. Bias tape adds a nice decorative trim detail to arm and neck opening, hems and pockets, and can be used to bind raw edges inside your garment.
It is pretty simple to make your own single- or double-fold bias tape. Well, not as simple as picking up a premade package at your local fabric store, but if you make your own it will coordinate perfectly with your project!
You start with a piece of fabric that you have squared off. You can make sure the edge of your fabric is square by taking a T-square ruler and lining one of its edges with one of the selvage edges. Then take a long ruler and line that up with the other edge of the T-square. Mark a line following the long ruler across your fabric to the other selvage edge. Your fabric edge is now square.
Now use this first bias edge as your guide to make your other bias lines. I am making 1/2 inch double-fold bias tape, so my bias strips need to be 4 times that, or 2 inches. After measuring and cutting I have several 2 inch bias strips. Each of these strips has unsquared ends. Cut off these triangle-shaped end pieces.
Now you have several rectangular pieces of your fabric cut on a bias. Let’s sew them into one long strip. You sew the strips perpendicularly to each other with right sides together.
Here are two that have been sewed together. When you open the fabric with right sides up, you get a strip with a diagonal seam. Sew the rest of your strips to this one making sure you keep the seams going the same direction (i.e., don’t accidentally turn your strip around so that the diagonal seams run different ways).
