i crocheted up one square in each color to check that the gradient was fairly smooth.
then i tested the concept of alternating with white squares.
i ran the colors on the diagonal rather than in straight lines. that made it easier to crochet together but alternating squares means i really need to have a whole row finished before i put them together. that is fine for a regular blanket but not great for a temperature tracker. i didn’t want to waste the swatch though, and this yarn is almost impossible to frog, so i added a border and it will work as a little blanket for a pukifee
