Yesterday, after the sun had set and I couldn’t take a photo, I finished piecing together the fourth vinx.
Earlier in the day I had managed to make and affix two ears to the purple vinx:

and I then continued working through all of the daylight and beyond until all four vinxes were pieced together with the ends woven in trimmed.
So this morning, before I left on a series of errands, I posed the vinxes and captured this snapshot of the four vinxes:

Then, when I returned in the afternoon and the light was better, I was able to get them in other poses.
Here they are all stretched out:

and here they are, folded:

The only thing missing from my original vision?
Fur.
I had planned to attach fringe all over in a manner similar to what I had done with this porcupine:

My first effort was a bit over the top, but not necessarily in a good way:

I then regrouped, thinned the first effort, and then tried something shorter that would also be trimmed:

I’m still not sure how this fringe fur adventure will unfold, but I know that I will learn something; I just don’t know what.
