So I made a start with that teeny-tiny hook and the embroidery thread leftovers...
I'm keeping all the knots to the outside of my work. The plan is to turn the piece inside out when I am finished, and then hide the knots with a lining.
But I'm starting to quite like the look of them... so that plan might change!
Still not sure exactly what it will be when it is finished... but I'm running out of thread fairly quickly - look how small the ball is getting already.
