Krystal makes afghans which are donated to charity. She has created this pattern and shares it freely. Her only requirement is that you agree to send her a completed square. Above are two of the squares I'm sending her. There are pictures on her blog of squares sent to her from all over the world and of some finished blankets. She has even started a Yahoo group to help people with the pattern. If you crochet, you might want to check it out at http://krochetkrystal.blogspot.com/ .
