I use the Dritz glass headed pins they are very thin, but sturdy, and I paint all the glass heads with dark blue nailpolish, so I can readily see them when sewing. I purchase them from Amazon, and they came in a tin box, which I like. You can get them in two sizes 1 3/8 or 1 7/8, my Bernina sews over them as well, if I miss taking one from the fabric.
