I found that this pattern is by Paul Boer and was in the November 2008 issue of
CREATIVE WOODWORKS and CRAFTS magazine.
I think the back issues are only $5 each with lots of patterns but, if that issue is
not available you can contact Bob Duncan of Creative Woodworks and Crafts magazine and
see if you can get just the single pattern.
Let me know if you have any success.
