Last weekend, Casapinka designed the beautiful Ripples Make Waves hat--a free Ravelry pattern download--in support of the people of Ukraine. She suggested that since the pattern is free, perhaps people could donate what they would normally pay for a pattern--roughly $6--to a reputable, vetted charity that is providing aid to the people and refugees of Ukraine.

Other designers have also posted patterns to make in solidarity with Ukraine. These patterns as also free, and they, like Casapinka, have suggested that you donate what you would normally pay for a pattern to a reputable, vetted charity. You can find those links here:
