I have finished building the Dreadknight and I have canned the tabard idea, in theory it looked good but as mentioned by my friend Ead might have looked like an emergency escape slide. Having sculpted it and put it in place I can safely say that it looked like Little Timmy the Terminator was on a day out with mummy and daddy at Crealy Adventure Park and got to go on the Dreadknight Slide.
So instead I have gone with a hanging pennant. This is a happy compromise that will give me a point of visual interest and somewhere to do a little freehand and it also helps to visually balance the model as the lower part is rather sparse.
ready for painting.
