She used standard black thread I assume. There was nothing unique about it. I had her pay extra attention to the corner where the edging starts and then finishes (after wrapping around the towel).
I bought a handful of the Cobra Supreme 530 Microfiber Towel and the edging came apart. AG sent me a few replacements but those too fell off after one gentle wash. I had to spend $15 at my local tailor to have his seamstress sew on the edging better on all the towels.
Although soft and thick...

Exterior Process. SSR1, Zaino Z2, 4* UPP, AIO on wheels and exhaust (my buddy requested this combo which actually turned out very nice...maybe not necessary to have 2 sealants but nice none the less)
