perspective grid

Palm here's the link for the psd file for the perspective grid
here's how to use it:
1. select the pattern layer, crtl+T to transform
2. right click and choose perspective
3. drag the corner to transform the pattern to shape
4. choose the grid layer and do the same transform to match the
pattern
5. use the grid layer as base for other pattern

here are some example I done, you can just use these.
Remember, the pattern is base on square, so you can flip the
grid 90 degree (distort the top) and it would still work
