simple wiggly wave lines in PS

[fifty]

OK this is my first ever mini-tut so don't be to harsh on me!

So I've been doing an antique style map and wanted to do some woodcut/wave lines around my coasts, there's quite a few other tuts on this site that deal with this subject but they all seemed quite involved for a novice like myself so I had a bit of a play and came up with this method.

Oh and I'm gonna write it out in as much detail as I can so I'll try not to assume to much prior knowledge

step 1. Make the stripe pattern.

new document 1pixel wide by 4 pixels high.
you want to make the top pixel black and the other 3 white
then 'Edit', 'Define Pattern', and either give it a name or keep the default.


step 2. open the map your wanting to put the wiggly waves around.
I'll use this amazingly complicated example :


P.S. If you haven't got a 'land selection' layer already then do this:
Duplicate this layer, 'select'. 'colour range' (white) fuzziness 200% and delete.
Change the fill to 0% and rename it to 'land select' or something else meaningful.
You can then ctrl click this layer later to select the land mass only in any other layer.
