Mum's box of lace

Over the past weeks I have been sorting my mothers house of 62 years which was bursting at the seams with all manner of things from 6 sets of cutlery to 18 packets of fertilizer for camellias. I found this box of lace awhile ago but couldn't bear to look closer until today and amidst the little rolls of lace I found 3 stocking boxes filled with their own little collection of lace. This is one of them. Now the question like everything else of what to do with these beautiful but probably useless little bits, short in length and discoloured with age. Any suggestions?
