To those good with computery graphicky things

I'm thinking of two possible background patterns for a quilt: a diamond lattice, with diamonds measuring 1" x 1.5", and a slightly curved version of the same, which you can see here. I'd simply buy the stencil, it's the right size (and apparently looks a lot better than the scanned-in version shown there), but the international postage is pricey and too slow, considering that the quilt has to be done for the competition deadline in September. Would anyone be able to create either of these for me, say as a PDF that I can print onto A4?
