Standard Flats

A stock of 10'x4' and 12'x4' double sided canvas flats has been suggested. In previous years this has been unfeasible due to damp problems in the arch but the new set store is designed to limit that, meaning flats will last more than one year.

Finally, I think it is worth looking at using cleats rather than pin-hinges for joining flats wherever possible. Cleats are much easier to get undone in a hurry, and just as strong as pin hinges. Also, there are no pins to lose, which makes life easier.
