WHAT I didn't know you could make the edge pen transparent! Thank you for sharing!!
Hope this is a good place to put this, I thought it would be nice to share some tips with using FireAlpaca that I have learned in the past!!
This one is pretty cool, and I find myself using it from time to time to help with drawing wings. It involves using the edge pen to do so. If this doesn't work for you, be sure that you updated FireAlpaca to it's latest version!!

But seriously good tut, I didn't know about the transparent thing either, and the lettering looks pretty cool.
