What to make when it is 95 degrees with 90% humidity??? A lightweight tee, of course. Cotton yarn and I have never really gotten along, and I find cotton handknits to be too heavy and bulky for my taste. So I stick with wool and wool blends even in hot weather. Surprisingly, they are quite comfortable. Wool can be lightweight and have good wicking properties; I think the key is the thickness of the fabric.
The yarn used here is a sock weight from Blacksheep Dyeworks on Etsy, and I absolutely loved working with it. Every time I see a Blacksheep Dyeworks banner on Ravelry, the saturated colors catch my eye. I finally dove in and bought several skeins and was more than pleased with the beautiful colors. The yarn itself is tightly spun and retains a beautiful sheen. Love love love!
I have two more skeins in a mossy green in my stash, and I'm already dreaming of what to knit with them. I'm thinking a henley top with elbow length sleeves. I was able to make this short sleeved top with about 600 yards, and with 850 yards in my stash I think I can make it, maybe even down to 3/4 sleeves. Using size 3 needles (probably a size 4 for tighter knitters) creates a perfect fabric that is lightweight but not see through, and comfortable enough to wear indoors.
What are you working on in the hot weather?
