I used a 4.5mm hook for this square and you can see that I worked one less row at the top to make the right gauge.
Also my 'waves' slope in the opposite direction on account that I'm left handed ;-)
I loved making this square...seeing those waves appear was magical! I'm loving that this blanket is purely about texture rather than colour. However, being the colour junkie that I am, I'm looking forward to working with my Dancing Around the Beach Huts colour palette.
