I quilted many years without a pattern--couldnt afford one--just looked at others and copied best i could.They mare all good--maybe not perfect but loved all the same.And as for the color wheel---well i flunked art in high school because i couldnt make a color wheel.Lttle did i know--i was partially color blind!!didnt find out till i went for a job when i was older!!I just pick material i like and go with it!!
