I LOOOOVE bias tape. Sure, there are lots of types of bias tape that you can buy in a shop, but making your own is so cool because you can use perfectly matching fabrics with the exact width that you prefer. You have total control over your project. But cutting out a gazillion diagonal strips can waste a lot of fabric and it can take a while to sew them all together. Luckily, your bias making experience is about to get a whole lot better because I’m going to show you how to make continuous bias tape easily with just two seams without wasting fabric!
I’ve already shown how to make bias tape with a bias tape maker as part of my Bias Tape Series, however today’s trick makes it a whole lot easier to make a LOT of bias tape so much more quickly. Basically we are going to sew the fabric into a sort of skewed tube so that we can cut around in a spiral while still getting perfect bias. It’s sort of magical!
- cut of cotton woven fabric, preferably a square, but not necessarily
- rotary cutter*
- cutting mat*
- quilting ruler*
- 25mm (1″) bias tape maker* for 25mm (1″) single fold bias tape or 12.5mm (½”) double fold bias tape, the size I use the most (or get a great deal on this 5-size set of bias tape makers*!)
- Collapsible sleeve ironing board* (optional but recommended)
- regular pen
Preparing the fabric:
1. Iron the fabric. Then use the lines on the cutting mat to lay it out straight and cut one edge with the cutter and ruler.
3. Cut the other sides of the triangle with the cutter and ruler along the 0° and 90° lines (bottom).
4. Cut the square from corner to corner, using the lines as a guide (above at left).
5. Line up the edges of the two triangles as shown in the picture above at right, right sides facing. Notice that one tip of each triangle sticks out a little bit at the top. (Look at the picture below for a closer look.)
6. Pin the lined up edge and sew with a 1 cm (3/8″) seam allowance.
Now we’ll start tracing the cutting lines!
