To make a cross (or other shape) similar to this you will need:
a cross shape template
a piece of plywood
a soldering iron
a fretsaw (or someone kind to cut it out for you)
My dad cut out the shape for me and we added a hook on the back to hang it with.I hope we can use the cross with Henry when he's older to discuss the meaning and reason behind his dedication. I've also included a few other photos of decorations from the day. They're fairly basic decorations as I'm time poor at the moment but added to the special feel of the day.
