I'm happy to present to you this idea, which is very effective thanks to the super quality and strength of your super magnets.
These memo pins are 'très funny' and can easily be made by children.
They will certainly be full of pride when they can give these pins to friends and family at parties and birthdays.
First choose an attractive character, print or copy it, or use a drawing done by your child.
I recommend a size of 5 to 7 cm, so you might need to reduce the size of the picture.
Then glue the character to a 3-4mm thick piece of plywood.
Let it dry for 24 hours then cut it out using a jigsaw.
