To make this blanket I have combined two joining methods.
The first is a continuous join method, which can be found around the place, here are some videos I like: https://www.youtube.com/watch?v=swro8-DaMXI&list=PLytkewzuOlZXtLFH7vf2pOHMHQhdfeYJO&index=4
and

The second method is the PLT (pull loop through) join as you go by Cypress Textiles (@cypresstextiles on Instagram). Here is her tutorial for the PLT join as you go: https://cypresstextiles.net/2016/01/21/plt-join-2/
And here is her tutorial for a continuous PLT join, similar to what I have used here, but using a single crochet (US stitches) border around each square: https://cypresstextiles.net/2016/03/05/plt-join-sc-continuous-jayg/

In this video I used a 4mm hook and Stylecraft Special DK. The colours are white, sherbet, cloud blue, turquoise and storm blue.
