The poem excerpt is from "Bobcat" by Elsinore Smith (age 13), from River of Words: The Natural World as Viewed by Young People, 2003 edition. Read the full poem here.
River of Words is a wonderful project, truly deserving of our support. You can read more about it, and view the winning poems and art in the 2008 edition, here. There are also links to the Finalist poems for each year, and these are fantatic too.
The poem can be found in full in Lisel Mueller's Pulitzer Prize winning collection Alive Together (Louisiana State University Press, 1995).
I'm experimenting with some print-on-demand products. A number of people I've talked to have recommended Spreadshirt for creating t-shirts and onesies. Spreadshirt charges a bit more than some of their rivals (a definite drawback), but have a reputation for better quality clothes and a better quality of printing. So I'm giving it a go.
My "Spreadshirt Shop" (which is still quite small while I check this process out) can be found here. Most of the items are for children, but there are one or two adult shirts as well, in organic cotton.
If you happen to give one of these items a try, let me know (honestly!) what you think of the printing quality. Or, if you've ventured into the print-on-demand realm yourself, I'd be interested to hear what your experience has been.
