For me, yes... too small to fool with. There will be three times as much fabric in the seam allowances as what shows on the front.
I did see an amazing example of the tiny 1/2" mosaic squares quilt at a quilt show last year. A man had made a full size replica of The Last Supper painting, using all 1/2" squares... most that he had hand dyed. It looked like a person's life's work. He had to grid off the entire painting, and study and match colors, half inch square by square. Just amazing, but definitely not for me to try!
