Here is an update from Brodie's Furever Mom:
Yes, Brodie, ever Col. Potter Kid gets his or her own blankie, lovingly made by a "Blankie Auntie". The Aunties donate their time and materials, then send the blankie to the foster home, usually within a few weeks of the little cairn's arrival. The blankie then becomes the cairn's very own and follows them to their adoptive home.
There is a video tribute to the Blankie Aunties on Media Central, via http://www.cairnrescue.com/, as well as instructions how to make the blankie.
Brodie, we're so glad that you love your blankie as much as you love your furever home!
