I just love these DIY projects for the garden that Mashable magazine have put together.
The Bottle Bird Feeder is fantiastic and would make a great kids garden project.
And these Sponge Water bombs will be a total hit with my niece and nephew and all you need are some cheap sponges and some string.
And these cool paraffin lights would look fantatic in anyones garden.
