For those that are so engrossed in this project that they are forming attachments to individual blocks I can report that the one with the pretty wiggly lines is now the left hand ground level block in pen three, while its partner left over from a project three years ago is the second left of the four blocks left over from this project so far. So after spending three years lying next to each other in the garage they've been split up! Who needs Eastenders when you've got a quality soap like this going on in blipworld.
