The first attempt at translating my design is done.
I'm actually pretty pleased with the way that it turned out. I think the different stitch patterns have created the look of different textures in each of the sections, but keeping the same stitch patterns for each colour has provided some cohesion to the piece as a whole.
The only thing that I'm not sure about is the purple, I don't if it stands out from the background enough .... but it is growing on me. I think the piece needs a darker colour for a bit of balance. I'll live with it for a while and see.
I started with the black felt background as I thought that of my three ideas for working the design this was going to be my least favourite but now ...... well I'm thinking that this could end up being the one I submit as my resolved piece. I'm still going to try the other ideas though so time will tell.
