fabi chicki ... how very clever!
and, pictures to boot! That technique should ensure a smooth backing, and to do that alley thing with your pins ... that is really clever!
(Can you tell that when I pin, I don't pin that closely? <G>)
The pictures are really helpful to people like me who can spell all the words, but sometimes can't quite get the mental picture to fine tune up into the frontal lobes. Thank you!
