Firstly, Print your mandala here.
Colour in using your favourite colours. You can use colour pencils, felt tips, paint, anything you like.
Next, carefully with a paper craft knife cut along just the dotted lines. Using a pen or pencil roll these petals forward to create the 3D petals.
Decorate further with embellishments if you like.
I put my finished work in a deep frame to hang up.
