Hi,
Thanks for the reply, I meant I would do the increase through 5 'knit' rows (start with a knit row and do the 2 increases, then a normal purl row without any increase) - that would make 10 rows in total.
Your reply looks great, I will have to think it through, I am a bit slow on this!
Here's the link to the pattern:
