These bags provide good protection from dust, dirt, and to a certain extent from damp. They are better than putting a map inside a box or tube because of the risk of abrasion from rough handling. Rolled documents can be handled and lifted without stress.
Materials needed:
Unbleached Calico
Unbleached Cotton Tape
Small luggage labels
Cardboard Roller/Tube, large diameter Archive quality or covered with acid-free manila
Equipment needed:
Sewing Machine or Over-locker
Tape-measure
Scissors and Pins
Roll document around the roller and secure with *calico bands tied with tape.
Measure the rolled document - see diagram. 
Two measurements are needed:
a) The length, plus the diameter of the end of the roll, plus 4" or 10cm for the tied end.
b) The circumference of the roll, plus 2"or 5cm.
Cut a strip of calico, the required measurements.
Cut 2 or more tapes, the circumference plus 14"or 40cm. More tapes would be needed if the document is very long. Space them at 18" or 45cm. intervals.
Place map in bag tie and store.
Maps & plans that need to be stored flat can be stored in ‘Melinex’ polyester sleeves with or without an acid-free mount board. They also provide some support to fragile documents. However, do not use if the item has flaking ink or surface decoration such as gold leaf. Select a size that is around 1" or 2cm larger than the document. These are available from the Conservation studio at Devon Record Office.
