Aunt Beast is a character in the Madelyn L'Engle book, "A Wrinkle in Time." She was an alien on a distant planet who had many arms and was covered in soft, warm, brown fur.
Perfect!
One year, for Christmas, I did a cross stitch picture of Aunt Beast, (this time a crocodile) and Uncle Beast, (this time a brown furry beaveresque animal). They have treasured it.
So, when we were invited to help celebrate their 60th wedding aniversary I knew just what to do! No gifts were permitted but who could argue with a card?
