I also starch as I fall in the prewashers camp
I know everyone has their own best practices. I think what ever works for you works. I'm always looking to improve. I do the pre wash because if it is going to bleed or shrink I want it to do before I attach it. Now about the starching, is it when you ironing after you have washed it before you cut it? What products are you finding work best? Ironing isn't something I know alot about. Starch I know zip about. Please advise.
