I am not a perfectionist, but I like things to look nice. If it is something for my personal use, I don't worry as much, but if it is for gifting, then I take a bit more care. I have learned over the two yrs. I have been quilting how to get most seams/corners to match - not even worried about points yet. I try to work with patterns/fabrics which are forgiving.
I feel this is something we do for our own personal satisfaction - being able to use something we have made or being able to give it to someone else -- whether family, friend or community service. I too, am not concerned with juried shows, hanging my work in a gallery, etc. Relax and enjoy what you are doing - you will gain SO much more satisfaction from it.
