The quick answer
The easiest ocean crafts for 3-5 year olds use the recycling: a paper plate octopus, a loo roll jellyfish, a bubble wrap print turtle and foam sailboats. Keep googly eyes, washable paint, child-safe scissors, PVA glue and foam sheets in the cupboard.
On holiday Verity made a very pink octopus from a paper chain craft kit, and a little fleet of foam sailboats. Here are our favourite ocean crafts, most using stuff from the recycling.

Paper plate octopus
Paint a paper plate, cut it in half and stick on eight paper strip legs (curl them round a pencil). Googly eyes are compulsory.
Loo roll jellyfish
Paint a cardboard tube, snip the bottom half into strips for tentacles, and hang it from string.
Bubble wrap turtle
Paint bubble wrap green and press it onto paper for a shell pattern, then cut out a turtle shape.
Foam sailboats
Foam sheets, a straw for a mast and a triangle sail. Add stickers for flags.

Handy supplies
