I have two baptism gowns ( one 120 years old one 30 (mine and my husbands great grandmothers) that I need to store properly. I know nothing about this kind of thing the box kits I find online with just a simple acid free box just the box is 70$ and then a pack of acid free paper is 20$ can it really be 90$ to get a box to put the things in? Anyone who knows a better/cheaper way I would appreciate it!
