Update on assignments

Marylou and Kathy asked for an update:

• Margaret set the assignment 'Lines', which she announced early, strictly speaking it is due just before Prague.
• 'Blue' is a suggestion I made for an extra-assignment, only if you have time and inspiration, to fill a bit more of the wall space in Prague.
• Gillian's assignment 'sketch' was announced here, and is 'due' by the end of the month.
• Barbara's assignment 'repetition' is even further back, and I was really late finishing...

Hope that gets everybody up to date.
