I've only done one quilt with very small pieces (an Elizabeth Hartmann). It was very difficult. I used a seam guide and got thru it, but tiny pieces are not my favorite. I'm good with 2 1/2 inch squares but 1 1/2 are awfully small. Depending on what pattern you are doing, it could be possible to use 2 1/2" squares and just have a larger quilt.
