Thanks limey! It's gratifying to find someone who finds me as dazzlingly clever as I do!
Here's my construction journal. It's the director's cut, meaning little was actually cut. Not true, fewer than half the pictures I took are included in this DIY story. Here we go.
I made a template of the petals so I could trace out some fairly regular petals over and over again, so I'd have fairly regular flowers.
Twelve of them were done in red leather. This shot only shows some of the tracings. I'd made the first few flowers freehand. They turned out on the small side, so I made these petals a lot bigger.
The extra relief at the intersection of the petals in this detail shot allows the bottom of the flower to be more compact. There will be a stack of these petals for each flower.
The thirteenth rose is a black one.
