restoring old linens
I apologize if this has been asked before, but I tried posting this question in search and no examples came up. I have some old linens, bedsheets, pillow cases, fancy pieces that have yellowed over the years. some that are mild may be due to age but others, like the pillow cases are very yellow and I suspect this is from chlorine bleach, though no one has admitted using it. I really would like to restore them to their original whiteness as they have a lot of my great grandmother's embroidery on them. Is there any way to reverse the horrible yellowing on old sheets etc.?
