Please consult the attached instructions to construct this 12-inch variation of the Lattice Block.

[NOTE: There were some errors in the original file. Thanks to QuiltnNan's eagle eye the file has been corrected. If you downloaded the earlier version, you'll want to download the one posted now (0911am 4/6/2014).]
