Well, that was an adventure.
Dyeing the Fabric
I hemmed both pieces all the way around prior to dyeing, because I had time before I could go dye shopping. This might not have been the best idea.
The dyeing did not go as expected. The orange piece dyed just fine. The dark blue-black lost almost all its color after the rinse, remaining a (lovely, but not what I was looking for) dove grey. I used enough dye for the fabric by weight, so what was the problem? I didn't use the Rit Dye Fixative, so maybe that was it. I bought a bottle and did it all over again, this time in the washing machine (because my shoulder got sore from all the stirring.)
Same. Darn. Thing. Only now with a few color blotches. Sigh. I went ahead and used the grey fabric.
Sewing the Tunic
Pinning the orange "interfacing" to the longer grey "undertunic" was harder than I expected. Here is where pre-hemming the fabric was a bad idea, as the edges did not always exactly line up. I did my best to fold and fiddle things into alignment. I sewed around the neck slit first, cut it open, flipped the orange through, and then sewed down the orange on the outside. The neck slit wanted to rip, so I reinforced each end with some buttonhole stitch (on my machine). I suspect on the original, this was woven in.
I turned it inside out again and sewed up one side, keeping about a 5/8" seam allowance except where I wanted the armhole to stop. I angled out to the very edge of the fabric there. See, since the layers were already hemmed, I wouldn't be folding them under. If I'd just stopped without angling it out, there would have been a 5/8" step from the seam to the sleeve.
Turning it right-side out, I laid the yellow ribbon down along the waist at this point. I used a commercial yellow satin ribbon, I think 1.25" wide. Obviously not period, but I was not up for dyeing a long strip of cotton yellow just for this.
Inside out again, to sew up the other side and tuck the ribbon edges under themselves to prevent fraying. Then, because the hem wasn't even, fold up one side so that it was.
Cats!
My wool felt arrived in time. I blew up the image of the cat and used it as a pattern. The yellow eyes were more of the yellow ribbon, stabilized with Wonder-Underish stuff.
The cats were all sewn together. I have lots of experience sewing felt faces, thanks to my son's insatiable need for felt plush toys! Yellow eyes to red eyes to face; white teeth to red mouth to face. I considered needle-felting the pieces together, but I don't have a lot of experience with that, and the examples I've seen of it didn't have crisp lines.
Cultural Appropriation Panic!
It was at about this time that I stopped to wonder if these were jaguars. I still don't know a lot about Incan culture, but I'm pretty sure jaguars were sacred animals. Was I making the equivalent of priestly vestments for casual wear?
I did a quick Google search for jaguars in Incan art. They uniformly look different, with large fangs always represented at either side of the mouth. Plus, there are several species of smaller wildcats in South America. The Pampas cat can have a black coloring, and its (modern) range includes the Rio Ica region where this tunic is from.
So... okay. I might still be doing something wrong, but at least it's not the sort of big, obvious thing.
Finishing
The only thing left was to attach the cats to the tunic. I seem to have gotten the proportion slightly off - when I positioned the cats with their faces about the right distance apart, I had more margin by the sleeves. I am okay with that. One cat got sewed down. I got impatient with the other cat and Wonder Under-ed it.
Accessories
Wikipedia and other lousy Internet sources describe the llawt'u headdress as 'cords wrapped around the head' or 'a turban.' Most of the images on the Internet are only from the front, and show something like a wide headband. Sometimes there are ornaments at the center forehead.
I found some great pictures of Inti Raymi, a re-enactment of an Incan sun festival in Peru. While many of the photos center on the more spectacularly-dressed nobles, here are as close to some 'regular guys' as I could find. In one or two images, I thought I saw a simple tie in the back.
I tried a Storvik llawt'u, with a red and white striped band and a drekkar ornament. It... did not really go with the tunic. At all. So I got a piece of trim with appropriate-ish geometric designs. The feathers were bought for quill-making but have found new life.
Fringe at knees and/or ankles seems to be a thing in the pictures from the manuscript linked to last time. I bought some nylon fringe in red - doesn't really go with the tunic but I also wanted fringe for another project and red it is. I stripped some of the fringe from the ends of two lengths and tied them on at the knee.
Sandals were of llama rawhide. Not having any to hand, I'm substituting in a pair of Roman (?I think? Sylvanus Perrin made them ages ago) leather sandals. I also found a pair of gold leaf-shaped earrings - big round circles would be better, but I don't have any.
