This morning, Chris and I headed to the National Centre for Craft and Design in Sleaford, to see an exhibition devoted to 3D felt. (Sleaford is rather an out of the way place for a National centre of anything and I do wonder why it was chosen. The building itself is rather like Dr Who's Tardis, but in reverse - it looks much bigger on the outside!) I asked whether I could take photos and was told I could, so, I wonder if you would like to join me at the exhibition? You would? Excellent…
