I only learned and started quilting this year, and had a lot of angst over not having my seams and points match properly. But, when I shared my feelings about this to my other sewing buddy, she quoted to me what the Amish said about not sewing so perfect, it is because "only God is perfect." So, I just chug along, trying my best to just take my time.
The main thing about quilting is to have fun doing it--perfect or not. We are our own worse critics, so just "Sew Happy!"
