It's hot outside, it will only get hotter and it's going to stay hot.
Today in my beautiful city, the forecast is for temps in the mid-90's and a heat index that will climb way past 100 degrees. Did I mention that it is also humid? Because it is. It's the South and it is summer. (For those of you reading from the other hemisphere [and I know you're out there--hello, how y'all doin? Glad to have you!] save this post for six months hence when it will apply to you!).
For some, this means abandoning knitting altogether. My friends, let us not be hasty. There are some wonderful things you can knit during the hot summer months. Now, lest you think I am out of touch with the weather, remember I have lived in either Texas (flippin' hot) or South Carolina ("it's not the heat; it's the humidity") for most of my life. While, yes, I have knitted a Big Wool Bag in July, I don't recommend it for every summer. Think small projects (Socks!) or projects with lightweight yarn (shawls!) or something using cotton (dishcloths!). Also, never underestimate the value of a well-placed ceiling fan.
I am currently working on a cowl with alpaca and wool yarns. It's a hot project, though not itchy because the yarn is quite nice. I will bind off and block it soon, and pick up the needles for what could be an epic THREE (3) pairs of socks going at one time (because I do occasionally take my own advice...). Also in the works--a summery wrap made from cool cotton, and a dishcloth or two.
Despite the heat of a Southern summer, knitting is part of my life and as such is a comfort and a distraction from the challenges of the weather. So my advice is to find something that is compatible with your weather, knit it, and don't forget to stock your hurricane supplies with fresh yarn and some back copies of Cast On, because as they say down here, you never know when the next big one will come our way.
Wishing you good weather wherever you knit!
