Thank you. I sprayed the whole stencil in grey tones, then i got an extra piece of cardboard and cut out a square relating to how big I wanted the blue to be, then I just re-sprayed every layer with that square covering it so the blue wouldn't get on any other parts of the canvas. I dunno if it was the easiest way to go about it, but it worked out alright
Yeah, the Hugh one was a bit of a trial thing for me, first time I worked with coloured layers. It was a good idea in theory I think, but I know what you mean. I might re-spray it when I find more time.
