I don't assemble using the same method, so I'll simply identify a paired set of spoke holes. starting from the valve and with you facing what will become the right side of the wheel, the 1st two holes to the right (1 o'clock) I'll call nos. 1 & 2. These will be "pulling spokes, and go to opposite flanges on the right side of the hub at about 2:30 or so. The rim has offset which dictates which is to the right flange and which to the left, but the spoke closer to the valve will go to the hole in the hub one half space to the left of the other., ie. if the 1st hole is to the left flange, that spoke will be to the hole slightly to the left of it's opposite in the right.

When helping 1st timers I suggest looking at the rim 1st and seeing if the spokes moving to the right of the valve are marching right/left, or left/right. If marching right/left in the rim, they have to march right/left in the hub, so the left pulling spoke would be to the right of the right pulling spoke
