There are some things I can live with (like dust and leftovers for supper and unfolded laundry) and some that I need to at leasttry to make better (like that corner where two--or more-HST's meet that just isn't quite right on a quilt that is being gifted to a family member or QOV or...) but only to a certain extent. If it really bothers me I try up to 3 times. At that point number 3 is the way it stays. Period.
My biggest hurdle is colour coordination. I spend more time auditioning and second guessing myself on which fabrics to put together than I do in scrutinizing my intersections. I am really really trying to make my choices and just live with them.
