When practicing try words that have 2 or more of the same letter in them,like NO TRESPASSING,to get good letter consistency. The first letter style I was taught was a speed letter so i could go with my mentor to letter windshields at car lots, the second was a speed script then a straight block letter later on.I found learning those letter styles in that order is easier because you can start out loose ,then tighten up your skill as you move on to each letter style. I also had to learn my straight letter without using any tape on top and bottom,I was told all that tape would do is "handicap me" . Once i learned without using tape ,I was allow use it.The whole handicap thing went along with using a mahl stick too, I had to learn to use my other arm as a mahl stick.
Another thing was, I wasn't allowed lettering signs that were laying flat .I was told having to deal with the weight of your body can cause problems when pulling lines ,everything was lettered straight up and down with a slight angle
I mainly use blue handled Luco brushes.My favorites are #6,7,8,10,12 .Some people pallet their paint on a magazine I pallet mine right in a cup and on the edge of the rim,I clean my brushes in paint thinner and soak them in motor oil.When mixing my paints I add a few drops of kerosene or a chemical called SMOOTHIE (creates better flow) I thin my paint with paint thinner or BBQ starter .I use a popsicle stick and after a while you get use to feeling the right consistency of the paint by the way it stirrs and flows off the popsicle stick.So once you get a good flow of paint for yourself...stir it around to see how it feels in the cup.
Everybody was taught to sign paint differently these are some of the ways i do
