You may already have done something similar to this before, such as granny squares or bunting, but I thought that this one looked a little different so might be something you’d like to experiment with. You can alternate row colours quite easily by the looks of it too.
Home-made At My Place have already put this in UK terms, and looks relatively simple.
(Edit: I made a mistake and misread the pattern – it’s in US terms, not UK! Therefore:
US single crochet = UK double crochet
US half double crochet = UK half treble crochet
US double crochet = UK treble crochet)

Thank you for the links to my blog! Please note that I use US crochet terms, not UK ones! ;oD

Thank you :> We always include translation guides within the posts for those using US terms.
Good to know!!! ;oD

With a similar granny triangle pattern I made a big shawl last month as well 🙂 I love granny triangles now! Will try this for bunting as well 🙂 Shawl info on http://catstitches.wordpress.com/2014/08/11/a-shawl-for-my-mum/ 😉
