Santa’s Postbox

by Amy Collins June 8, 2018

Sending letters to Santa this Christmas? Use your Gratnells tray to make your own postbox for your classroom this festive season. Don’t forget to share your pics on Twitter and Instagram using #WhatsInMyTray!

Learning outcomes

You will be able to:

  • Select and use a variety of materials and techniques to make a post box.

You will need (per post box)

  • 1 x Shallow Gratnells (F1) tray for the post box
  • 1 x Shallow Gratnells (F1) tray with an insert to organise your resources
  • 1 x A3 piece of red card
  • 1 x A5 piece of brown or gold card
  • 1 x Large bag of cotton wool balls
  • 1 x A5 piece of black felt or black card
  • 1 x Small pot of sequins
  • 1 x Tube of biodegradable glitter
  • 1 x String of tinsel
  • 1 x Pot of PVA glue or bottle with pointed applicator
  • 1 x Glue spreader
  • 1 x Roll of sticky tape
  • Your letters to Santa!


  • Organise your resources into a Gratnells tray <insert type used> insert and place the tray in the centre of the work area so it is accessible to all.

What to do:

  • Take photographs at each stage to capture your work.
  • Cut some red card to size so that it fits across the front of your shallow tray.
  • Cut a window in the red card big enough to fit your letters and cards to Santa through.
  • Tape the red card to the rim of the tray so the space in the tray can catch the posted letters. Tip: Leave the top unsealed if you want to be able to remove your letters later.
  • Glue some cotton wool balls around the window of your letterbox.
  • Cut two pieces of black felt or card to make Santa’s belt – these should be slightly shorter than half of the width of the tray. Glue these into place leaving a small space in the middle.
  • Cut a rectangle belt buckle from some gold or brown card and glue into place in the gap in between the belt pieces.
  • Spot glue on the red card and stick on the sequins to give the post box some festive sparkle.
  • Tape the tinsel around the rim of the tray.
  • Stand your tray on it’s end somewhere in the classroom where it can rest on a wall or be safety secured.
  • Write letters to Santa or Christmas cards for your friends and post them into the post box ready to be shared before the Winter break.

Other things to try…

  • Create a reindeer or an elf themed post box instead or design your own ‘traditional’ post box.
  • Share photographs of your Christmas creations on social media using #WhatsInMyTray.
