I hoard cotton lace. Mojo's scarf is made from metres and metres of the stuff - I gathered it haphazardly onto several strands of hat elastic, before adding pom-poms and plastic beads on finger-knitted yarn.
The yarn was my grandmother's. I aquired it a few years ago - as her only granddaughter, I was lucky enough to inherit all her needlework materials and sewing equipment when she was no longer able to use them. She turned 96 last October!
