Version 3: FoldedStart by cutting a strip of bias that is six times the width you want your final bias to be (yes, six, not four like the other two). So in order to get the same 1/2" binding I need to cut a 3" strip of satin. My favorite way of doing this is with a rotary cutter, but employ your own favorite way of cutting continuous bias, there are a ton of ways out there. If your bias is not long enough for your edge piece strips together to get one long enough. Once you have a strip cut fold it in half wrong sides together and press.
Pin the raw edges of your folded bias strip flush with the raw edge of your fabric.
Sew the strip down. The width of your seam allowance will be the width of your final bias binding, in this case 1/2" seam allowance equals 1/2" bias binding. Open the seam, seam allowances to the bias tape side, and press open. Then fold the bias around to the back and press, then pin in place. The bias should just barely cover the seam.
From here you can finish the bias tape either by stitching in the ditch like you did for Version 1 or by slipstitching by hand like you did in Version 2. This method renders a sturdier, more durable edge that is bulkier than the other methods:
