Making bias tape can result in a lot of fabric that is wasted when it is cut flat on the bias (unless you want lots of little seam allowances). Then someone devised a method where you create an offset tube. I don’t know about you, but I was never quite satisfied with my results.
And then….and then! My couture professor showed us a method of making bias tape that is just amazing. She is the first to admit that there will be a section that isn’t on the true bias but for most uses of bias tape, it won’t be obvious and doesn’t cause any construction issues. You end up with a ton of tape, so start somewhat small. I think I ended up with 12 yards of tape from a 18″ x 36″ piece of fabric (the size I used for this tutorial).
No Waste Bias Tape Steps
1. Cut a rectangle with a 2:1 ratio. For this tutorial, I used an 18″ x 36″ rectangle.
2. Fold in half to make a square.
3. Sew around all raw edges with a 1/2” seam allowance. Turn corners
with needle down. Essentially, sew the entire thing shut.
4. Mark line from where stitching hits corner to the fold on the opposite
corner. Flip and mark the opposite corner to corner. Check to make
sure the opposite corners have been marked. If you were using an
imaginary x-ray machine, you should see an “X”.
5. Carefully cut through only a single layer on the line.
6. Turn over and cut the other layer. You should end up with a tube.
7. Press the seam allowances open.
8. Match edges carefully. With a rotary cutter starting at one of the folded
edges, cut through both layers part of the way. Do not go all the way
across to other fold! It should remind you of an octopus. Don’t forget to add seam allowances when figuring out how wide you want each strip to be.
9. Carefully turn the piece and draw a line from one row to the row next to
it across the uncut the area (this is a similar concept as “the tube”
method of making bias tape)
10. Start cutting along the lines you just drew to make on amazingly long
strip of bias tape
11. Be geeky like me and admire how many yards you got out of such a small piece of fabric.
Happy bias tape making!
