It is best to perform smudging at a time when you will not be disturbed & to create a sense of ceremony when you smudge your space. Make sure you open windows during this smudging & open any cupboard doors, hot press, drawers etc… As they are places energy can get trapped. Have a heat proof bowl or abalone shell nearby so you can hold it under the bundle as you go round smudging to catch any glowing herbs that may fall. Light the tip of your bundle & then gently wave it in the air until the tip begins to smoke. Use your hand or a feather to gently waft the smoke where you want it. 

Start at your front door & move in a clockwise direction around your house. Paying attention to corners, behind furniture & under beds, you can recite a smudging prayer that resonates with you. 

To cleanse objects such as crystals, jewellery and pretty much anything you like. Again light the bundle & wave it until the fire is out and the bundle is smoking then hold your object over the so it can be cleansed by it as you recite your cleansing prayer. Remember as with all magic and spiritual practice your intention is everything.  

Don’t forget to smudge yourself and others
