Join Bias Strips
Sewing together two pieces of bias tape with a diagonal seam makes a sturdy seam that’s less bulky and less noticeable than a straight seam. Here’s how:
Position and pin bias strips perpendicular to each other with right sides together and raw edges aligned. Draw a diagonal line on top bias strip from top left to bottom right.
Sew on marked line to make a diagonal seam.
Trim seam allowance to 1/4".
Press seam allowance open.
Fold and press edges toward center of bias strip.
Fold pressed strip in half; press to make one continuous folded bias strip.
