Yep! that way any moisture will be peramently trapped in the clothes, ensuring that they rot.
I cannot believe the amount of total bollocks being spouted here.
I suppose in tehse days of suburnaites living in selaed double galzed battery farms, and drying clothes by putting them in a heated tumble dryer, the facst of living more or less out doors have been totally lost from te fulture.
mould comes from damp stuff sealed up and put away.
You 'air;' things by hanging them out so air can circulate. This DRIES them. It even - gasp - used to be done on washing lines OUTSIDE. I wonder why we bother to ventilate rooves to stop them rotting. OBVIOUSLY the only way this can be done is to seal them, up totally and run humidifiers in them. I cant understand how all the stuff stored in my shed for years hasn't gone rusty or rotted away. It must be a miracle! No less than all the flags that are flown on poles, however do they not rot when exposed not only to the dangerous un-dehumidified COUNTRY AIR but also to the dangerous cancer inducing SUN and worst of all RAIN. Oh my gosh. If ONLY we had listened to these suburbanites in their sealed little boxes, our flags might last MONTHS instead of the TENS OF YEARS they do last.
I cant understand why anyone would actually USE a shed when patently, conditions inside them are so dreadful that you would be no better off leaving things out in the rain and the sun.
Unlike houses, people do not sit in sheds sweating, take steamy baths in them or cook in them. Thy have no sources of moisture over and above what is in the air.
Get real folks. Keep the rain off, let the air circulate, stuff wont rot. 2000 years of experience says so.
