It basically shows you how to make your fabric into a tube where you the seams are sewn before you cut it into strips. This probably wasn't the best fabric to use as the pattern didn't match up in the seam joins. It definitely did work and made most of the joins neat & tidy. I think it would become quicker the more you practiced and understood the process.
While making your own bias binding is a little time consuming the end result makes it all worth while.
