You don't need help from us...you're doing fine on your own. Many quilters buy patterns and kits and it works for them. I like to take a pattern or an idea and put my own spin on it. I've never bought a kit because they don't usually have the fabric in colors I like and following a pattern to the letter, well that never happens for me...I usually have to change the size or placement.
My advice to you is to go your own way. Your quilts already are pointing you in that direction. Even the 1/4 inch seam isn't a "must have" as long as you take your wider seam into consideration when you're planning your quilt. And, the longer you quilt, the better and more accurate you get.
