the excel spreadsheets are my doing, but the .pdf images of them are not. those images of the excel breeder spreadsheet project were turned into .pdf files for folks without microsoft excel (or the free viewer). although i did not make those images, i think if you print them, cut them out, and fit them together, you will find they will make one chart for foliages and one chart for flowers.
might i also suggest that you download the [spoiler] version of Virtual Seed Tray, which has similar functionality, is interactive, and does not require microsoft excel?
