The weather in the UK necessitates a cardigan or cover-up most of the year. I would estimate that 10 out of the 12 months of the year is for general knitting. With the other months taken up for something lighter.
Currently on my needles is a short sleeved top by Sublime - Morocco which I am knitting in cotton kapok. I normally don't wear handknits in the summer but felt the need for a change this year. I do knit cotton hats for my grandson, and little girly tops for friends babies, but not much else is summer weight yarns
I would say that the majority of my knitting is more autumn/winter based. I love making blankets and throws for the home, these I can just pickup and do at any time. I also knit lots of hats and scarves.
I do find that my knitting tails off anyway over the summer months as my time is taken up in my garden - some shots of the garden over the last few years
Plus IF, the weather is hot, there is nothing worse than sweaty palms and yarn!
Hope that you are all enjoying Blog week, so many posts to read so little time. Thanks for all the great comments thus far
