I haven't sewn much this year because I'm painting a Scottish Mural for a client! 5 months down and she's nearly done! The wall is roughly 10 metres squared, and I'm using Dulux Weathershield paint and mixing my own colours.
If your wall is porous as
this one is, I recommend using round artist bristle brushes and not
your typical flat brushes or rollers for walls. :) B.
