What silk should I buy?

Since the dollar now is only worth 6,8 swedish crowns, compared to 7,4 last month this might be the perfect time to buy some silk from Denver fabrics. It's just that I don't know what to buy, because I don't know what I want to sew from it. Except that I want 1 yard of this to line a buttoned hood in periwinkle wool. wouldn't this be a nice veil for the 12th century when they still had coloured veils? Or this, but I think it's a little warm for my colouring.

So please tell what I should buy (not limited to those above) and why.
