I've found out that the directions for the #15 oatmeal strip (3 1/2 by 19 in the instructions) seem to be 1/2 inch short. When I lay it on the bottom house section, doesn't line up.
If you look at the bottom grass section that also aligns to the house unit, it is 3 1/2 by 19 1/2....
I HOPE that someone looks at this and corrects the pattern.
Still having fun!
