Use a pillowcase as a laundry bag while travelling
When you travel, you always want to keep your dirty laundry separate from your clean clothes. Stick a pillowcase in your suitcase and toss in the dirty laundry as it accumulates. When you get home, just empty the pillowcase into the washer and throw in the pillowcase as well.
Use a pillowcase to dust ceiling fan blades
Have you ever seen dust bunnies careening off your ceiling fan when you turn it on for the first time in weeks? Grab an old pillowcase and place it over one of the ceiling fan blades. Slowly pull off the pillowcase. The blades get dusted and the dust bunnies stay in the pillowcase, instead of parachuting to the floor.
Turn a pillowcase into napkins
Who needs formal linen napkins that need to be pressed every time you use them? Pillowcases are available in a wide array of colours and designs. Pick a colour or design you like, and start cutting. Prevent fraying by sewing a hem on each side, or simply finish with iron-on hemming tape. You’ll have a new set of colourful napkins for a fraction of the cost of regular cloth napkins.
