Shingle template in process

I put a small spot of hot-glue on the back of the bottom row to hold them in place on the template. The subsequent rows are only glued to the prior row so that the paper template can be easily removed later.

Those Fiscar's scissor trimmers have been awesome at cutting the shingles and siding. They make precise cuts without destroying the delicate pieces. They also were useful for trimming some of the rough edges of the larger pieces before sanding.
