When in doubt follow the instructions Margaret!
The HD3QBEM wants some bed socks and from the knitting pattern stash we dug out an ancient pattern. The instructions said to be knitted on four double pointed needles.
What a humbug, I don't think that's necessary, I said to myself and proceeded on an ordinary pair.
But!! The instructions are written that way for a reason and I have come to a full stop.
I think this is why I prefer embroidery over knitting.
