I remember doing this many years ago. I made trays (flat base, wooden square beading nailed on to make troughs to make the beams in, about 2cm square and 10cm long). Pupils would make different compositions to test.

Couldn't find how to pin it so I have made a WhatsApp group to save the posts to. Best thing I could think of at the time.

Hi Dan. New to the blue butterfly! Do you know if there is a way to bookmark posts so I can review them later? I like to keep all my resources links in one place.
