Masking tape needs to cover the tip of the upper roof panel so glue does not get all over it when joining the wall and roof assemblies.

Here is an extended section of the K-Hinge that allows the roof panels to be hinged on the outer edge of the wall, but tilt inward. You can see there is a blue tint to the stitching. That blue is from the super fine tipped sharpie I used to draw the parallel pair of lines that are one inch apart. The lower piece of canvas is 9 inches wide versus the standard 8 inches. The upper piece of canvas is 7 inches wide compared to the standard 6 inches. The gap in the middle is 1 inch wide.

The wood block is under an inch in height. But it keeps the panels separated so that the 1 inch of hinge material between panels does not get bound up during the gluing process. I folded back and glued the 1 inch wide gap material onto itself.

Here is the height of the wood blocks.

The 7/8 inch wood blocks allow the 1 inch tall hinge material to compress and bow just a bit. This was not an issue at all during assembly.

Here is the finished roof and wall assembly with the 3 wooden blocks acting as spacers. This is the first of this type of K-Hinge that I have made. Two more panels like this need to be finished. Then all of the wall panels need to get their lower edges covered and the anchors installed.
