Jumping late on to another bandwagon. This one's all about colour and I like colourful things, so I don't know why I didn't sign up weeks ago.
The idea is, there's a colour theme for each month. March's theme is red and pink. You can use the theme however you like. Knit things in those colours, find pretty things in those colours to share on your blog. Whatever. I like that sort of no-pressure participation.
