Here are a few fiber tools I have made:
Drop spindles. Everyone needs a pink drop spindle, don't you think? The pink one is a toy wheel , the other is a piece of walnut that was turned by a local woodworker.
Knitting needles topped with handspun.
Jeweled stitch markers and copper wire stitch holders.
I've also made fabric knitting needle holders and cozies but forgot to take pictures. However, you can go here for inspiration and a pattern or two.
What do you make for your making?
