can same one tell me how to make them?

what l have read about these is to just lay them out on the ground.

1st get a milk jug. If it is white, then get some black paint and draw your goose. If it is clear then take some white spray paint, and make the inside white. then use the black paint for your drawings. After you do this, then tie a line with some weight so that they will no flip over in the water, and your all set.

Milk jugs are used as part of the spread for snow geese, and, as long as they're white, do not need any other work except the installation of anchors to keep them from blowing away.

Snow geese spread tend to be use (as are the flocks). So in addition to standard decoys, hunters expand the size of their spread with other white items: milk jugs, diapers, even sheets of newspaper. The idea is to suggest a flock of birds feeding in the field.
