Now that we have the bias strips, I'll show you how to join them.
Here's the photo of the strips again.
Step 5. Before joining the strips you can square off the ends like this. I have joined them before without squaring them off and it works fine. But, I have a geometry/spatial relationship impairment and it's hard for me to visualize and join the seams in the correct direction on the first try.
Then cut along the lines. You must do this with all the strips.
Step 6. Join the ends. IMPORTANT: When you're doing this make sure that all the seams face the same way and that the longer strips don't become twisted. I've made both these mistakes before and it's very annoying.
Continue until you've joined all the strips together.
Step 7. Now sew them all together to make one long strip.
Step 8. Press all the seams open.
Step 9. Now you're ready to add the cotton filler cord. NOW IS THE TIME TO REMOVE YOUR PRESSER FOOT AND ADD YOUR ZIPPER FOOT. YOU CAN'T DO THIS WITHOUT A ZIPPER FOOT.
Lay the cord in the middle of the strip and fold it over so the edges meet and the cord is inside against the fold.
Sew as close as possible against the cotton filler cord. This is what it looks like when you're done.
The next post will be the last. I'll show you how to attach the cording on the underside of the covered chair seat.
