When Apple first introduced Leopard (Mac OS X vers. 10.5), one of the really neat features was the Stationery feature in the Mail application. They had supplied a number of professionally designed templates making it very easy to send out very cool emails. Some of them even had the ability to change the base color! This was especially important in the "Birth Announcement" Stationery.
At some point over the seven updates to Leopard, the original Stationery were replaced with even better constructed templates. Unfortunately, one of the sacrifices were that fewer of them had the color change feature. Most disappointing is that the "Birth Announcement" is now only available in blue! What if you want to announce a girl? What if you're announcing your new High-Def Entertainment System? You're going to need/want something other than blue!
Last week, I set out to learn how to make my own Stationery files for Mail. Part of the process is to understand how the current stationery works. It a lot easier to modify what's already there than to create new from scratch. The results are also instantly gratifying like we've grown to expect in this day and age.
