Round and Round I Go

In my recent hunt for sleeveless tunics and cardigans to knit for the girls I found some absolutely beautiful designs on Ravelry and Etsy and other people's blogs but didn't reslise until after I had printed several out and ordered one online that they were all made using circular needles. I've done a lot of knitting over the years but have never done anything on circulars. I sifted through Mum's needle collection and found she had quite a few but not only do they have to be the right diameter but they have to be certain lengths as well. I wanted to use wool that I already had so it took a while to find the needles that would suit a pattern and my wool. I decided on this pattern. (By the way this lady has a pretty cool blog with lovely patterns (some free and some for sale in her pattern shop). Then as I was about to cast on the pattern tells me to use The Old Norwegian Cast On Method...the what?? So I jumped on Google and found these instructions. It looked way too complicated but I worked it out in the end and apparently it gives a more elastic edge.
I found it quite odd using the circulars as I didn't know where I was heading with the pattern but once I got going it became a bit addictive because I wanted to see what would happen next and you just keep going round and round....and round...and round

It's still on the needles (or is that needle??) but might be finished in a couple of days so will post a photo then.
