Greenhouse: Building a geodesic dome greenhouse, 1 by tropicalaria

As in the top patches, the center seams have to be positioned, secured and lathed before the outer seams.

At the edges, the bottom patches have to be leaved under the top patches, and the triangles have to be under the trapezoids. There are only five points around the greenhouse where the corners of the patches meet, and for each of these joins there are five corners which have to be layered in the right order. All of the edge seams around one of these vertices are under the lathing before I work on the corner. I tack down the lower layers with a single staple while I pull the upper layers into place so that they can all be pinned under the same lathing.

There is 6-12" of margin on each piece which greatly simplifies positioning (each patch is up to 12' x10' but the center point and interior cut have to be positioned to with 1/2" vertically, horizontally, and rotationally) but also allows each of the corners to be secured under all of the other seams of the vertex, giving me greater confidence in the integrity of these points.
