I like working in moderate sized batches. I'll cut enough to be able to make many blocks, but not a whole quilt. I like sewing for a while, pressing for a while, squaring up for a while, repeat. Some times I'll be in the mood for larger batches and/or multiple cycles, sometimes I'm in the mood for smaller batches and/or only one cycle. Most of the time, I don't sit down with a fixed goal of either time or output - I keep going as long it's fun and I'm not making too many mistakes. When I start making more mistakes, it's usually I sign that I'm getting tired and would better off taking a break. (I'm picky with my own sewing, and will rip out and re-do seams when my points and/or seam matching are not spot on.)
The idea of doing everything assembly line style where I do nothing but sew, say, a bazillion half square triangles is not at all appealing to me. I like to see blocks being created even close to the beginning of the process, as I like to admire them and start to play with them to see how the layout is going look.
