It's hot this summer - not that I complain! I love warmer weather - and I know that one or the other doesn't like to knit when it is very warm. I think it all depends on the project you want to tackle and my tip for summer knitting is: Small, quick and easy projects. Like for example mitts, which will be needed soon enough when the weather becomes cooler.
I recently republished the pattern for a favourite of mine - To and Fro Mitts. I just love the zigzagging lines and how neatly the thumb gusset emerges from one of the lines.
The pattern includes three sizes - woman's S, M and L - and each pair requires only about 250 yds of yarn. Doesn't this sound like a perfect summer knitting project? The pattern is now available from my Ravelry store, here: To and Fro Mitts.
