The perfect place to hide your treasures!

What will I learn?

1) Tin cans REALLY are a crafting ‘super resource’, always keep a stash of them in your cupboard.

2) Even though a ‘treasure box’ is a children’s craft staple, that doesn’t mean it can’t be given a new twist.

2) PVA glue is not just great for glueing… it can also be mixed with paint to create fake ‘snail’ soup!

Time to get started…

The lid

Remove the lid and label from an old tin can (1). Use a compass to draw a circle the size of the inner diameter of the tin can onto corrugated cardboard (2). Cut it out and ensure it fits snugly onto the inner rim of the can (3).

The fake soup

Saw a metal spoon in half (4). Cut a small slot into the cardboard circle, the size of the sawn end of the spoon and 6mmm from the edge - the spoon must fit without gaps (5). Now make the ‘snail soup’ by mixing PVA glue with green and yellow poster paint or acrylic paint (6).

Place the tin can next to a wall, insert the cardboard disk and push the bottom of the spoon into the slot, leaning it against the wall for support (7).

Place a few lumps of plasticine (substitute pieces of snail!) onto the cardboard disc (8) and pour on the glue until it reaches the top of the rim (9).

Leave to dry for 2-3 days. Then paint the surface with a thin layer of PVA glue for a nice gloss finish (10).

The safe

Measure inside of the can and workout the diameter and height required for the ‘safe’ to fit loosely inside.

Using these sizes cut 2 discs from corrugated cardboard and make one a hollow ring. Glue and wrap thin card around the discs to create a cylinder (11). Use tape to hold the card while the glue dries (12).

Print and cut out the ‘safe’ artwork and spray mount or glue it around the cylinder (13).

Use a craft knife to cut around the door, leaving the hinged side attached (14). To prevent creasing remove a tiny strip of artwork from along the hinge (15). Finally, cut out a semi-circular finger hole on the right of the door (A).

Open the door and score along the inside of the hinge for easy opening (16).

Cut and glue card tabs onto the inside of the door and door frames (17), this helps lock the door (B) and prevent it from opening inwards (C). Finally, remove the snail soup ‘lid’ and glue it onto the top ring of the cylinder (18).

You can push the ‘safe’ back into the tin can until the fake snail soup ‘lid’ rests on the inner rim, like the first photo above. Who’d ever discover that!

Give it your own unique twist

Kids love secret treasure stashes (especially if they have nosy siblings). If this one is too much effort, try something different - how about hollowing out the inside of an old book - I’ve always wanted to make one of those?
