Pins. I'm the first to say that I hate them. I hate pinning, hate taking out pins, hate everything to do with pins. Pretty pins, safety pins, quilting pins, all pins. I much prefer just winging it and "finger-pinning" as I sew.
But... pinning can have great results. I'm working on a super secret present right now, and although I hate doing it, I am using pins in the process.
What are your thoughts on pins?
