Pete,
I have seen lidded yarn bowls but very rarely and I did not have the wood to spare to do a lid or two, so I stuck with the traditional style.
Derek,
They are all finished with Danish Oil, currently they are sat waiting for the oil to polymerise before the first 4 go off to their new homes. At this rate, I'm going to have to find another log of something to make more.
The two little holes, are they decoration, they are something I'd always seen in yarn bowls, so thought they were for the knitting needles to poke through, or maybe you are right, don't know.
