Basically I spray painted an empty Cadbury's Roses tin white. You will probably need to spray three layers and be sure to leave it to dry thoroughly for at least a day so as to get rid of the paint smell and to avoid paint coming off when the lid is pressed down. Next I reused the stencil that I made here for the bench cushions. You can find out how to make your own sturdy reusable stencils from laminated paper here. You can of course buy a stencil but it's very easy to make your own using your own designs or any old picture you find from Google Images to tailor your theme.
Now you can proudly display your new cake tin rather than hiding it at the back of a cupboard just in case you might need it one day. Or wrap one up in see-through cellophane dressed with curling ribbon and make somebody's day with a gift.
