Honchey--I understand what you are asking. I've never used the pinking blade, so am not sure. I would say test on some scrap material to be sure. This is what I would do...if you want a 2 1/2" strip, trim to square up/pink the outside edge, then put the ruler at 2 1/2" and cut...then try sewing a 1/4" on each side and measure in-between...if it is right it should be 2"...does that make sense?
I had Mon-Thurs off work. I spent some time with my sisters and their families at our mom's house on Wednesday. DH's mom came here for lunch on Thurs. I took a nap Thurs afternoon instead of going to the clubhouse. I might go out and sew a bit yet today. We should split some firewood since the weather is so nice today, but not sure anyone really feels like doing it....
