of the partial frame members 70 71 72 so as to form a compound frame member 73 a joining element is not needed to connect the partial frame members because the interdigitating shape of each end of each partial frame member performs sufficient alignment of the connected partial frame members fig7 b is a top view of three connectable partial frame members 74 75 76 having gem decorative pattern on its decorative side joined so as to form a compound frame member 77 a joining element is not needed to connect the partial frame members because the interdigitating shape of each end of each partial frame member performs sufficient alignment of the connected partial frame members fig7 c is a top view of three connectable partial frame members 78 79 80 having a rounded pebble decorative pattern on its decorative side joined so as to form a compound frame member 81 a joining element is not needed to connect the partial frame members because the interlocking shape of each end of each partial frame member performs sufficient alignment of the connected partial frame members fig7 d is a top view of three connectable partial frame members 125 126 127 each having an antique floral decorative pattern on its decorative side and each juxtaposed so as to form a compound frame member 128 the partial frame members 125 126 127 when abutting against one another also form a continuous antique floral decorative pattern alignment of the partial frame members of each frame member can be achieved using a joining element to join each partial frame member to its neighbor s and or using a straight edge placed.
