I tried several different fabrics for the last neck section- here you can see the first two and then the one that is more blue right above them. I really like the fabric that is right below the chin for rock shadows. Much better than the stark dark ones on the right side of the piece. I’ll replace those. I only have a small piece of that good shadow fabric though, not enough to do what I need to.

Checked the shelves and there is no more. So I dumped the scrap basket. More often than not, I can find what I need in there and this time was no exception!. Only one more small piece, but at least I can spread it around and augment with something else. One of the good things about this technique is that it uses small pieces so I can often work from scraps and I don’t worry about waste because they are so small. I don’t plan to purchase any new fabric for this piece and will work with what I have.
I decided that the last neck piece was still not right so I divided it, using one of the rejects on top with a blue shadow at the bottom.

Much better, so I sewed the seams, softened the facial blues and added background above the neck. Now I think the chin is too white against the dark rock so I’ll have to do something about that. No wonder it takes so long!
