you really do need to figure out where on your machine this is. If your quilt is made up of all the exact same blocks, then just being consistent will be just fine. As soon as you try to piece one block with 3 seams next to a block with 2 (or 4 or 5) seams, you will start to have problems.
That's just not true. All of the blocks will be the same size, no matter what blocks you make, if your seams are consistent. The seam width may, or may not, affect the final size of the blocks, but they will all be the same no matter how many seams are in them. Otherwise you'd never be able to make any quilt with more than one type of block in it.
I never use scant seams and it's never made any difference worth mentioning, in fact it makes for flatter, squarer tops and a much happier quilter when they're done.
