Start by using your brown in the middle of a tic- tac-toe, your focal fabric on two corners or all four corners. that is a nine patch, you said you wanted the brown to be cut. It will end up with a brwn in corner of four blocks, start thinking of where you want your focal fab-, now the tac blk above the brwn it you puta dark fab- above and below, you will have a dark fab- in all four blks. If you put two light blks on the second row tac blk on each side. when cut you will have focal-fab+drk+lght in all four squares.
