Okay, thanks for the help!
First off, my bad. I am having some growing pains moving from adobe and procreate, and was frustrated that I was spinning my tires last night when all I wanted to do was PAINT!!!
There are a lot of fine brushes in Affinity Photo, I didn't see the proper way to access them, so I went about trying to create my own. At least I learned some stuff along the way.
@NotMyFault: I realize that the tutorial I posted is DESIGNER, I believe that all of the brushes you create are usable in all of the AFFINITY programs? Thanks for helping!
@iconclast: Thanks, I looked up how to make Texturized Intensity Brushes and it looks easy enough, will try later.
If there is a definitive tutorial for creating brushes and brush sets, that would be a great thing to share here, I think, to help future help seekers. I'll return and share if I find one.
