Well, it didn't take very long and I thoroughly enjoyed knitting it:
Kate Davies' Northmavine Hap
I have changed the colour way a bit as I wanted cream but still wanted an overall blue effect.
I have reluctantly left it in the shop on display but really want to take it home and wear it all the time.
For all the information it is on my ravelry page here
Rosie is also making this in another colour way so I look forward to sharing that with you too.
