I am laughing because you must be talking about ME, the me who was an exuberant newbie many years ago. I had more fun picking the fabric and sewing seams together. "Quarter inch, shmorter inch, precision is for anal people!" That was how I thought.
It's a personality thing, truly at first, and then one learns that precision in each step--hard as it for some personalities to deal with because it feels like science instead of art, work instead of fun--actually makes the final project a joy instead of feeling like a waste of time when things don't come together as envisioned.
In fact, I am only on my 4th quilt ever, and the first with a teacher. We are doing a sampler wall hanging by Alex Andersen which I think has too many of a certain boring (to me) blocks--the rail fence. It also called for 4 flying geese blocks which I was having a devil of a time with after umpteen wastes of time and fabric.
In my heart I wanted the quilt to have a pinwheel because the darn thing is a story quilt about my childhood in Kansas where windmills dot the landscape. And I love, love,love pinwheels. So instead of 1 of the RF and 1 of the FG blocks I made 2 PW blocks. Teacher was looking at my work and said "These pinwheels are good even though they're the wrong block."
I defended myself. "They're not wrong, they're my choice." And I explained my choice. It just bothered me that she would call it a "wrong" block instead of asking me why I chose a harder block/block not in the pattern" when she had kept saying, "It is YOUR quilt YOU get to decide what goes in it."
And, BTW, I am an art teacher so I understand that need for personal freedom and the students who don't really care about the techniques as much as the fun of creating. Give her time. Her mistakes will force her to get that 1/4" seam
right. She may "zone out" when zipping along with her machine, like I do. My teacher found spots where the seams were about to come apart and she said, "I would fix them now while you can. Ten years from now it would be a lot harder." When I heard that, it compelled me to redo. (Plus she kindly offered to rip out seams for me!)
