I've been meaning to create an online exhibition of this wonderful work ever since.

As teachers we try hard to create audience for the work of our students.  The sheer logistics of organising a competition for creating models of DNA from all manner of materials and to have entries from all over the world coming by post makes me wince!

But there you go, Stefka is that kind of teacher.  It's taken me a while to get these uploaded but here are the pieces of DNA artwork which came from all over the world and Stefka had exhibited at the Natural History Museum in Sofia, Bulgaria.
