I have five shirts down. Three more to go---one has interfacing and just needs to be cut square. I find it easier to cut out the front by cutting along the sides of the shirt and up to the sleeve and collar seams and then put on the interfacing and then cut out the square. I had a bit of trouble ironing and pressing the shirts and getting them wrinkle free (ever end up making more wrinkles with your iron?) so if I just cut out the general piece I needed I could iron that flat and then put the interfacing on. So far so good.
I think I'll get interfacing one of the two remaining shirts and call it a night. One shirt is double sided and that might take a little more precision with the generalized cutting so I'll leave that alone until tomorrow. With the other shirts I could cut more towards the back if I worried I was going to cut into the space I wanted, but I can't with the Paul Grey shirt (in case you're wondering, Paul Grey was the bassist and died earlier this year...I got something a little more special in mind for that shirt so I don't want to mess it up.)
