You can get the idea from this quarter of the block.
The ugly is camo'ed pretty well, but the rule is that half the ugly must be used in the front and while half the ugly is used in the construction of the block, half of each corner triangle is cut off so really only one quarter of the ugly will show. So I am not sure it will qualify ... who knew it would be such a serious undertaking.
You can also see that the pieces don't perfectly align at the top of the coloured diamond - so I will do a re-cut and re-sew later. I really just wanted to see what it would look like.
