I also enjoy Jenny's tutorials. And because 99.9% of what I make is for my family, I don't stress over seams and points that aren't 100% perfect. For me, I enjoy the sewing and quilting process. If I stressed over it, it would feel like a job and then most of the pleasure would be gone. If someone wants to take my things apart and check my seam allowances or check my points, then go ahead. Life is to short and I have way to many projects I want to make for me to worry about perfection.
