Not the best pic - doesn't show the variations in color as well as I'd hoped!
I used James Brett Marble Machine Washable 100 percent acrylic in a color called "Dye". I can't recall the size needles though so I'll have to update that later! (* Size US 8/5.0mm needles).
It didn't feel itchy while I was knitting it but it has the few times I've worn it!
I love the colors in it! The dusty blue reminds me of an autumn sky and the yellows, oranges & browns, from dark to light, remind me of the first leaves beginning to change colors!
