Decide whether you want to use the finished pot for planting or for decoration. Turn a plain terra cotta pot facing upwards for planting or upside-down for hanging décor.
Use acrylic paint to cover the pot in the color of your choice. Use green, blue, pink or other bright colors for a more cartoonish octopus or grey or brown for a more realistic octopus. Let the paint dry overnight.
Paint on the octopus face on the front of the pot. Glue on googly eyes as an alternative to paint.
Trace the shape of eight octopus legs on a sheet of craft foam. Use craft foam that matches the color of the painted pot. Cut out the leg outlines with scissors.
Arrange the eight craft foam legs evenly around the painted pot. Use craft glue to attach them in place around the edge to complete the octopus pot.
