Tulle - look Mum, no Photoshop

There are ten thousand gadgets and gizmos to produce FX, And there's a million and one Photoshop plug-ins to do this, that and the other.

How about trying something really boring - liking buying meter of tulle for $1  and holding it in front of your subject.

You either have to grow two extra hands or you ask your subject to hold it. You can use it for straining your mull wine as well.
