I do alI the things you mentioned, but don't let it bother me as long as my quilts come out ok. I do some things to perfection, others don't come out so good. One day they will probably all find a home somewhere.
I have been making quilts for about 30 years, and have learned a lot since I joined the quilt board. Some things I will probably never use, because they are too complicated for me to enjoy doing. Other things I have tried have improved my quilting.
