My current prototype folds down into a small circle.

It folks out like a tri-fold wallet, with three circular areas to clip stuff to.

Can I do this in text?

The outer circles fold inwards, over the main circle. There is a flap that covers the top half and holds the outer folds in place. There is a pouch in the main circle and and the two smaller outriggers would be just large enough to cradle a small cell phone and a palm pilot perhaps.

I am debating materials. Leather is nice. So is leather and canvas. I figure if I did the whole thing in leather, along with it's contents, it would most likely be to heavy. So some parts could be canvas. Pleated perhaps, along with elastic, to easily draw in or out as needed. The outriggers would have a little latchet loop that would hook on to a knob of some sort in the center, under the flap where it would not be seen. It would fold as a kilt does, over to the right.

I read in a book that the sporran was meant to be an entirely practical device, something that could carry a man's kit so that he might live out of it. Back then, it might have been tobacco, maybe a bit of tender and flint, coins, odds and ends. Men today carry a good bit more... But we don't want a purse. Many men wear cargo pants... I see TONS of businessmen around here with pants loaded to the gills with gadgets. Times have changed and the sporran should adapt. We have all new styles of kilt making but sporrans are still much the same.
