I just wanted to add a note to my previous post on getting even corners.
I said I usually just put one pin in whereas some say they put in two pins, one on either side of the seam.
I was sewing some blocks together again just the other day, and my corners constantly seemed to be off, so I figured I would put in two pins, immediately on either side of the seam. And, waaala, my seams came out pretty much perfect every time. So, now I know, taking the extra time to put in two pins, really works.
It amazes me, that after many many years of always only doing one pin, I now am going to keep doing two pins. :)
