River terrain ...

I've been searching for a while for some affordable thin plastic sheet with which to create some river sections. I have two purposes in mind:

1. Two sections of shoreline suitable as waterways for use as terrain for 'DBA armies whose home terrain is 'Littoral'
2. A means to create wider rivers for other games. In particular I have a 1915 scenario in mind fought around the Suez canal.

Murray found some plastic sheets used as kitchen cutting sheets, flexible, but just the right size.

A single section of 'river bank

Two sections butted against each other to form a section of a wider river

The sections placed to form a river the length of a 6' table

I'll need a few more sheets to create some curves of various sorts. Onwards ....
