I have to agree with press. I used to sew a lot of clothing for myself and our daughter when she was a kid. I thought getting out the iron and board was a pain so struggled through sewing without pressing.
After a hiatus of about 10 years not sewing clothing I started back and decided to drag out the iron and the board. WOW...what a difference...especially sewing curves etc. Oh...and what fun it was sewing darts WITHOUT pressing...NOT.
My iron became my best friend. lol
