Pyramid-shaped boxes similar to the one in our story can be purchased at Beaucoup ($2; 877-988-2328). But if you want to make them yourself, like we did, here's how.
1) We scanned the runner fabric into a computer and printed the pattern on satin-finish Premium photo paper ($10 for 15 sheets; kodak.com).
2) We created a template for making the box. A similar one can be found at paperzone.com/cornerbox10t.html. Print out the template.
