I saw a tutorial online (I think it was Printcutsew, but I can't find it again) that showed pouring the screen filler onto the screen and using a squeegee as if the filler were ink -- and the result was a beautiful, filled screen with no streaks or clumps. It looked so easy!
However, when i tried this, my screen filler was very liquid (Speedball) and it didn't distribute evenly. It streaked and most went all over my table -- squeegeed out through the screen.
I must be missing a step. Can I thicken the screen filler? I've been using a sponge-brush to apply the screen filler, but it's not the most elegant technique and I have a lot of touch-ups that need doing later.
