This is a great first Fair Isle pattern. The pattern repeat is regular and easy to remember, so that you can concentrate on practicing stranded knitting. The purl rows make an interesting contrast to the stripes.
In Spotted Stripe pattern, 20 sts and 28 rows = 4"/10cm.
At 6' tall, I used to have a hard time finding sweaters with long enough sleeves. So I took up knitting to make my own sweaters.
