Writing stimulus - what's through the key hole? Make a link with stories, fantasy settings etc. Nice photo for a piece of extended writing, possibly even based on 'The Secret Garden' as I used as a stimulus last year with Year 1.
This brilliant invitation called upon the guests (yup those liggers who are coming to hang out, drink poor man’s champagne (cava), and eat free food) do a little work and make the pretty paper prettier. Although the invitations gave rough instructions it was ultimately up to the wedding guest how they decided to pimp their invitation. In this case, the leftover circles could be used as confetti on the big day.
