Progress

Having taken one look at the Lemmings-like interface for the social aspects of the eastercon (while noting that the teeny-even-on-a-big screen video links were at the top of the screen where my varifocals "do" distance and hence everyone I "met" was going to be a blur) and having failed to find the email that allowed me to set up a login to access programme via a saner route [no I don't want to spend Easter wandering around a pixellated space station trying to find a programme item]) I decided it was all too much like work.
Takes a deep breath, ends rant....
I'll just have to embroider instead. Progress has been made:

I attempted a green-man type design in one of the gaps which proved too large and not sufficiently densely filled to work. Hard to reduced in size without many stitiches into the "filled" parts of the fabric. I don't enjoy half stitches on Aida.
So, the new plan is a castle, but split to accommodate the central motif.
