Miso wraps calls for much more yarn than is actually used to gain color variety. If you make the Miso skirt, you will have plenty to make wrap.

To make with less yarn, you will definitely need 1 ebony, 1 white, 2-3 skeins “for a one other color version”

There is enough yarn left from the Miso skirt to make the wrap as pictured. See pattern MISO SKIRT
You can reduce the number of skeins used by doing a one or two colorway with the ebony and white for checkered board
