Are you making Casapinka's Ripples Make Waves hat? It is a pattern that Casapinka has written in support of Ukraine, and she has made it available for free, simply asking knitters who download it to contribute the price of the pattern to a list of recommended charitable organizations. Such a great idea!
The project calls for 225y of DK yarn in any shade of blue. This collection highlights yarns that would be perfect for this project.
The photo below is Casapinka's hat -- it is not made from a yarn in this collection, but any shade of blue works!
