Oh that is absolutely breathtaking! I have such admiration for people who can make such beautiful things. Wonderful that you have made such a kind and generous friend.
That quilt looks like "Lucky Stars" by Atkinson Designs. Type in "Lucky Stars" in the "Search" feature at the top of this page and you will find pictures of this fabulous quilt. The stars "float" so that you do not have to match up the points, etc.
Seeing that makes me regret more than ever that I can't crochet anymore due to arthritis. That is truly a work of art to be treasured. What a wonderful friend.
