Rosemary is the herb for memory, or remembrance, and as such it is often worn for Anzac Day (particularly appropriate as it grew wild on the Gallipoli peninsula) or Remembrance Day. Here is a simple illustrated poster to print out.
This Remembrance Day or Anzac Day "Lest We Forget" printable has relatively simple lines for cutting out - perhaps for a display on your board - or can be used "as is" for a poster.
Write about Remembrance Day or Anzac Day on this writing paper, choosing from blank, lined or handwriting lines versions. All have a banner with the words "Lest We Forget" at the top, and poppies for remembrance.
