Technicos: Joining Bias Strips

I sewed a number of samples using bias strips I cut myself,  for my sewing class.

1. Here's one way to join the strips

2. Then the strips will be joined on the bias

3. In these narrow sewing tasks, sometimes
backstitching to  lock the stitches,
causes the fabric to get trapped in the throat plate
 under my needle.
So.....

4. So, instead of back stitching at the beginning and end
of this small joining seam,
I use a super small stitch length of 0.5 at the beginning and end of
the seam instead. In between I use a regular 2.5 or 3.0
stitch length.
