Suggest you: Look at the block and find what you are dissatisfied with. Write those things down.
Then go back and find out how you can improve. If it seams not consistent, then find a way to make them more consistent. If they don't match up, then check each step up to that point. I took a class last year that the teacher said to measure each unit when finished before you sew the next. Know what is wrong and fix it.
Don't consider it one week of experience 12 times but a progression of learning each time to improve.
