Frosty Forest:Frosty Forest by Country Cottage Needleworks
I've stitched this series, and it's cute as can be. I stitched mine 4 across and two high, alternating house/forest/house/forest, but you can stitch yours all in a square if you include the center piece, which is THIS chart. I did not stitch this chart, but you totally can (see the second picture above for how it will look with all nine). They're also cute on their own.
