I will emphatically check the author's website, because I very much liked the font you used in your tutorial!
And I will also check your second site. I'm gonna lose my mind with this. I have learned that for physical covers, one need 1800 x 2700, 300 dpi, plus a suitable bleed, and MAY need wrap around for the whole book. But for e-books, they want it in a ratio of 1/1.6, 300 dpi prefered, also with a .25" bleed.
Once I learn your tutorial, I have a feeling that I am going to be doing it so many times I will have the darn thing memorized!2-3 times for each book -- and there will be 7 books in the series! (Geeze, I wish I were a clever programmer who could figure out how to automate this! Because seriously, I like this letttering effect better than almost anything else I have seen!)
