I don't know if this would interest you or not, but I thought that I'd share with you how I put together a diamond.
I begin by trimming the paper diamond.
Next I measure all of the sections.
I cut all of the required pieces.
I create a square in the square block, and trim to size.
I assemble the sides. I find the center by folding in half. I use the folds to align the centers.
I use half of a spring-clothes pin to 'finger' press the seams.
Once assembled, I lay the plexiglass template over the block and trim.
After I have trimmed the block, I separate the orts into useable and unusable piles.
Useable goes into a Ziploc baggie, to be scavenged for later block parts. The unusable, goes into my recycle bin.
A quick photo of the block, before pinning the paper to the block, and I am done.
