I know it is now the middle of July, but I have to report that the Correx 'cards' for the Queen's Celebration, all 90 of them, stood up extremely well for two weeks, in the pouring rain for most of that time; and when I took them down - they were in a good enough state to return them all to their creators. The materials were really easy to use, portable and permanent; POSCA water-based paint markers were tremendous, they can be used on most support materials. What is also useful, is they can erase any mistakes should you need to - as long as you let the 'mistake' dry first. Some of the young cubs were very impatient, but with my soothing, 'she must be obeyed' voice they waited the extra seconds.
So - POSCA pens are great! and so is Correx! Thanks to all, including ACoRP for the grant that enabled the exercise to be completed. It was a lovely day
