I like it when my points match and when the seams line up, so I spend a lot of time on the prep work. I find that correct cutting, pressing and a good 1/4" seam help ME with the final project. So I do all those things even if they seem a bit tedious at times. That said, I have learned where my tolerance for "mistakes" lies. I know when to take out a "booboo" and when it's OK to leave it in.
When it comes to quilting, I like pucker-free lines, so I spend the extra time doing it right. Admittedly, that is my LEAST favorite part of the process and I doubt that I will EVER like it. However, it doesn't mean I am going to slam the three layers together just to keep going. Puckered quilting would make me much more unhappy.
Probably explains why I have a huge stack of tops that need quilting. But still, I am having a ball.
