Lace is time consuming, but it's like doing a good crossword, it's kind of satisfying
Hugo, if no one asks, often folks don't think to explain
joejoe, the lace christening gown....do you know what it's made of ? is it silk, linen, cotton ? Just how old is it ? (generally these gowns are 1850's onwards, so Victorian/Edwardian) is it fragile or sound, and is it stained, or just grubby with age ?
If it's fine cotton 'lawn' as most were, (the cotton cloth is actually called nainsook, a Hindi word, meaning something like beautiful to the eye), and it's sound, then just soaked overnight in soft water with a little pure soap added. Don't scrub, just sapple it. Rinse, rinse, and onto a big bath towel to dry, gently moving it back into shape as it does so.
If the cotton is sound it'll iron easily, do it under a clean, smooth, linen teatowel though.
I make up lavender cushions to be folded inside such items, but not everyone likes lavender these days. I think it and fresh air a much more pleasant and natural scent on clothing and bedding than all the weird chemical mixes of fabric conditioner scents, but each to their own
The amount of work and the skill involved in making these tiny little gowns is inspiring
