String your loom as you would start any new looming project, warping one thread more then the number of loomed beads wide. Now string on a good number of edging beads, usually something round, not tubular like a Delica. This type of bead lays much nicer for this simple line edge. You will want to thread 5 or so more number of beads than the rows you plan to loom. These can be added after the initial warps are strung or string the beads first and warp the loom with the two extra warps stacked with beads.
