A friend gave me two skeins of linen-silk yarn that she'd dyed with logwood. It's so thin that she thought it might be weaving yarn, but I only know how to knit - and I love thin yarn.
Time to use my 1.5mm needles again! I picked stitch patterns that I thought worked with the colouring, cast on what seemed to be enough stitches, and knitted till I ran out of yarn. Result: thin, drapey scraps of fabric, perfectly suited for scarves that won't dangle in the ink when I'm printing on a cold winter's morning.
