A super special request and challenge

My cousin in New Mexico has a woven hat that needs a matching scarf.  This is the picture she sent:

She wants me to weave a scarf that is a close match.  Now I could take the easy way out and just pick out one color to match with navy, but that's just not my style!  No, I'm a take-it-to-the-limit kind of person!!

I thought about this carefully for a few days.  I thought about dying my own wool, but that makes it wool and I kind of lose the challenge of it being polyester.  So then I thought about ways I could weave with 3 or 4 strands of yarn that it just wouldn't make this kind of weave.  I really wanted to be able to match the original yarn of 3-ply pink, green, and cream and weaving with 3-4 colors wouldn't solve that problem.  Finally, I turned to my last resort: Dissecting already existing polyester yarn and re-spinning it together!  And it works!

Here is my trial run with very short pieces of colors that have nothing to do with these!

I'm pretty sure if I were to weave this together combined with another color, it would look like the above picture!  I'm terribly excited and I can't wait to try an even bigger amount of yarn!  I told her that if anything, I could make a very close "cousin" to her hat!

Here's what it looks like as 2-ply:

This is really cool!  I feel like I've hit upon a really cool new thing!  I see lots of visions... like I have very little of some ombre yarns that I liked... what if I mixed them with something else to not only tone them down but also stretch them further?!  :-)
