Using a sharp pencil, pierce a hole in the top of the a margarine tub lid. Put a blob of modelling clay underneath, to protect your table. Carefully poke a pair of scissors through the hole, and cut out the middle bit of the lid, so you're left with just the rim. Now cut one of the little metal clips off an orange net, and empty out the oranges. Place the orange net over the margarine tub. Try to keep the other metal bit of the net in the centre of the tub. Put the rim of the lid back on, and stretch out the orange bag as much as you can. Now make a hole in the bottom of the tub with the sharp pencil, and cut away the base so that you're just left with a circular rim holding the net in place. Cut away the excess orange bag bits! Now cover up the ugly rimming. Thread some ribbons through a netting hole, and round the rim. Keep going until you've covered the whole rim. Tie a knot in the end of the ribbon, then snip away the excess bits. Use more ribbon to make a hanging piece, and more strands to decorate the bottom. You could thread some beads or coloured feathers on! Try spray painting your netting, or using different types of tubs to make different sized dream catchers. Sweet dreams!
