I used the grid stencil to isolate bits of each A3 image. Or, as right, to overlay the two A3 images and take from both. Blue is often my chosen colour, though the later image is in much warmer tones.
As I was doing the colour wheel exercises, which is another story, I splodged and splished the spare paint on spare paper (good advice from Barbara, don't wash it down the sink, use it to colour paper in some way), and came up with this, which I then used for the next part of the homework (I was meant to use a magazine).
Here's what happened.
I extracted some smaller areas from this image; again using the grid to bring out certain parts. There is much twisting and turning and moving about of the grid, to try and get the bits you want to see, fitted into its irregular shapes. I worked each little area up on some cartridge paper (did I mention I'd treated myself to some felt pens; recently?!)
It's an interesting exercise as it encourages you to think of the image as a series of simplified shapes, which is what you need for an embroidery design.
All rather illuminating!
