You're very welcome! And thank you for your kind compliments!
I haven't used any of the top recommended yarns, so I can't compare them from experience. You might want to go with a yarn that is a blend of cotton and another fiber, since cotton can tend to grow a bit. I know Tahki Cotton Classic Lite is very popular, so despite that fact that it's 100% cotton, it may also be a good fit (though it will be somewhat shiny since it's mercerized cotton). Alpaca can tend to grow as well, so a cotton/alpaca blend might not be the best choice, though every yarn is different, and I don't know anything about the yarns listed and whether or not they grow. The Misti Alpaca Pima Cotton & Silk DK might be a good candidate if you can get it to swatch at the same gauge. I would be less concerned about the yarn being plied vs cabled than I would about the composition of the yarn. Do also check with your local yarn shop and see what they have to say.
