Thanks guys! I basically learned all my blending skills from heaps of practice and a ton of patience. I dont know about the rest of you, but I used to sit on a sunday whilst the omnibus of Sunset Beach was on and copy their eyeshadow!!!! lol. I fricking loved sunset beach, can't believe they axed it.
My trick is that I use the 231 to blend out the pencil I use to get the shape and then the only brush I use after that is a 242. I don't use any of the blender brushes i.e. 222, 217, 224, 239 etc. I find that using the big blender brushes to blend with are really inaccurate and actually give you less control. All you really need for blending is a medium sized (non fluffly) brush and light strokes.
I hope that helps someone and once again, thanks guys for the wonderful comments.
