I am an absolute fan of the Dennison Microtack, it is ultra small, and poses to problems whatsover, I sit at the table after layer up my quilt, I hold it with a few large straight pins, then slip my hand underneath the quilt and spread my first and middle finger apart and aim through the gap. I do it along the length and roll the quilt up as I go, so no reaching over any distance :D
Here's a picture of how small the tacks are :D
