Pattern help please

Hi,
I am knitting up a shawl but I don’t think I’m doing it right as the holes created by the yarn overs are very small and don’t look like the photo. image

The pattern is Beach Pebble Shawl by Helen Stewart https://www.ravelry.com/designers/helen-stewart

The main pattern is as follows;

1: WS: K2,p1,yo, purl to last 3 sts, yo, p1, K2
2: RS: K3, KYOK, K to last 4 sts, KYOK, K3
3: WS: K2,p1,yo, purl to last 3 sts, yo, p1, K2
4: RS:K3, KYOK, K2, yo, K2tog, K2 to last 5 sts before end, K1, KYOK, K3

Here’s a photo of my work so far.

It’s looking great to me :grinning: Remember that it will open up quite a lot after blocking when it’s finished
