As far as I'm concerned I would never (and no one else should either), consider making a block like that, unless it was paper pieced. As long as you will sew accurately on the line, you can't go wrong. Each section of the block will be the same and your block will come out perfect! This looks to take about an hour = 14 pieces in each 1/4 block. That's if you've chosen your fabric and cut it into strips already. This is pretty. You can be proud of yourself - it's OK.
