This is an Item Variation ID Spreadsheet for tsk and I, created as a way to organize the huge amount of information that I have on the subject of item variation, to help people who want to make their own items, or who want to help others make their items. It's very much a work in progress, so if you see something that you think should be added, or that doesn't seem to be on the sheet already, please comment on the spreadsheet or send me a message and I'll add it. To avoid too much confusion, the Google Docs spreadsheet is read-only but you can add comments.
