Three color version
Overlay mosaic crochet
You require three colors of yarn. For example, dark blue, azure and yellow. In these files I don’t give
an explanation of Color Changing & Carrying the Yarn. You can find a lot of useful videos on
YouTube and choose the one you like best.

The dark blue color goes single, the azure and the yellow at the same time.

950 yards of yellow, 2200 yards of azure)
