I'm not sure of the exact measurements used in WW I, but 12"-14" wide by 24"-26" long would be pretty close. You could use burlap potato sacks and (after modification) fill them with wood chips. (A filled bag with sand can weigh around 50 lbs.)
Potato sacks will not be the exact colour, but close enough. The mesh of the bag would be much more open than a proper sandbag, so trying to fill it with dry sand would be futile.
You may want to consider dropping in on an army surplus store (Queen and Bathurst in Toronto) as they usually have sandbags kicking around. You may get a deal on them and would save time and effort compared to making them.
Hope this helps.
