Hi, I'm inexperienced. I am not sure I understood the bias strip installation instruction.

Why do you sew the ends of the bias strip together before pressing it in half lengthwise and sewing it to the garment?

What if your measurement is off by just a hair and your facing is too small for the armhole? Wouldn't it be easier to cut a bias strip that is probably a little too long, then sew the strip to the armhole, and when you've got the strip sewn right side to right side all the way around the armhole, THEN cut the second end of the bias strip to match the first and sew them together?

I recently tried to make a chiffon dress using tissue paper as a stabililzer during sewing. I tore the tissue paper away after making the seams. This method DOES give you perfectly smooth, flat seams, but it is very messy and very time consuming. I was making a dress that had miles and miles of seams (don't ask). It was just such a miserable experience that after a while, I couldn't face it. I finally threw away the fabric and pattern to free myself to work on other projects.
