Storing kilts for a couple of years

[MacMillan of Rathdown]

I've stored mine folded in half (pleats out), wrapped in acid free tissue paper, and laid flat in a tin trunk with some mothballs for years with no ill-effects. Taken out after three or four years, then hung up over night, they are ready to wear with no ill effects or wrinkles.

I would think that sealing them in a plastic tube may have some adverse effect (the reaction between the plastic tube and the naptha in the moth balls), but have no "science" to back this up.
