Wall Street Journal hint grid (September 14, 2013)

In case you’re having difficulty with “Border Crossing” by Patrick Berry, the variety puzzle in this weekend’s Wall Street Journal, read the instructions again, particularly the part about extrusions being three to five letters.  I didn’t pay attention at first, and thus couldn’t mesh the first row with the downs that cross it.

If it’s still too tough, here below the fold is a hint grid to work from.
