Jo,
sorry I saw these a couple of days ago and meant to comment - but my feet have not touched the ground for about 3 weeks now, time (like everybody) goes by too fast.
I'm really liking where you are this idea, the more you experiment the more interesting the forms and shape combinations become.
I can see it being adapted to enable the use of boards of timber which would otherwise be difficult to turn into something as they would be too thin for anything interesting.
Keep up the good work.
