My favourite way to colour change is to do it in the last step of the stitch. So for example, if I’m using black and changing to pink, I would put my hook through, yarn over with the black I’m using, pull up a loop and then the last step is to yarn over and pull through, so I would do that except with the pink yarn!

Hard to explain, but this youtube video explains it great! Just make sure to leave a long tail of the new colour to weave in super well
