The chart is the same, but now there are examples of the chart on a worsted weight hat and a Bulky weight hat.

This is a stranded color work chart created to be added to a hat for the Science March, April 22, 2017. The chart is 10 rows high and 30 stitches wide. A 6 stitch repeat (delineated by the red lines) can be removed for a Bulky version or repeated to make the image wider.
