Border necessary for paving stones?

    I'm installing a shed on some 2x2 patio stones in an 8x10 rectangle. The
    ground is not level, being about 4+ inches higher on one side than the
    other. I plan to put about 5" on 3/4 gravel and 2" of Limestone screenings
    under the patio stones to help with drainage/heaving. But I'm wondering how
    much the gravel might migrate if I don't put a border (PT lumber) around the
    outside? I did something similar a few years ago with some penny pavers and
    marble chips (same gravel base) and I used a PT border to keep the chips in
    place. It worked out well then, but I hadn't really planned to go to the
    trouble this time. Although with my slope it might be a good idea.

    Any preferences?

    Yes, a border board will keep the ballast in place, especially with the
    slope, and help stabilize the edging 2x2 stones.
    I like to use Bend-A-Board, a reddish recycled plastic product, and be sure
    to use bendaboard stakes, too. Neither will rot, and will saw, bend, and
    screw with no splitting. Usually I use the 1x6 boards, 20 feet long. They
    also come in 1x4, 2x4, and other sizes. I place the border so it is just
    short of flush with the final stone surface, so the border board basically
    disappears, as it should, as it is a below-grade product.
