I now know that I will never go back to my old way of knitting as I've now 'cracked' the purl stitch and am building up speed on it too. I think the main problem was worrying about how I was doing and how slow it was and once I'd decided that it really didn't matter things speeded up!!!
It's not as fast as the knit row but I'm much more comfortable with it now and rarely drop a stitch.
In the pattern it said to start with the left front but me, being me, decided that as the back was the biggest part I'd get that out of the way first!! So here it is and progress is now being made on the first front.
The good thing about doing the back first is that it's reassured me that I've plenty of yarn to complete the project. Win, win!!!
