Clear Nail Polish
This stuff can be a total life-saver, and there are a bunch of different ways to use it. Dab a little clear nail polish on the pesky screws of your glasses to keep them secure (they are always coming out otherwise!). Brush a little bit over shirt buttons to keep the threads from coming loose and unravelling. Use it on nylons to stop a run. You can even use it to kill ticks that have embedded in your skin-- it will suffocate the bug allowing you to pull it out easily without leaving the head embedded (gross, but helpful to know if you live in wooded areas!).
Cosmetic brushes are great for sweeping out small, delicate crevices-- like the space in between the keys on your computer keyboard.
Use buttons as a tidy and easy-to-find way to store stud earrings. This is an awesome tip for travelling. Also great for at home if you keep your jewellery in a box instead of on a rack.
Here's another great jewellery-storing/travelling tip: thread a necklace chain through a straw and fasten the necklace before packing or storing. This will prevent tangles. It also makes the necklace easy to find in a travel tote.
Is there no end to the magical powers of cooking spray?! It's pretty handy in the kitchen, but there are some other great household uses for cooking spray too. Use it to stop door squeaks, or spray down your snow shovel before you begin shovelling to keep the snow from piling up and sticking to the shovel.
This may be my all-time favourite hack: use dryer sheets to clean your base boards. They work triple duty on this chore-- the softener helps pick up more dust than a dry or wet rag; the residue of softener left behind on the base boards also acts as a dust repellant; and it makes your house smell like fresh laundry.
Not just for the pool! Two nifty tricks you can use pool noodles for: cut them to size to fit inside your knee-high boots. This will help them keep their shape and keep them tidy while stored in your wardrobe (nobody likes boots flopping all over the place) You can also slip a pool noodle underneath a child's fitted sheet to help prevent them from falling out of bed. But make sure the sheet is tightly secured; otherwise the noodle will just slip down the edge.
Because there are never enough ways to organise jewellery while traveling... use a Days-of-the-Week pill box to organise and store earrings!
Use cute and colourful cupcake cases to hold pre-scooped ice cream for a party. This way you don't have to scoop as you're handing out cake-- they're already ready to go. Just place the filled liners in a muffin tin, and stick the tin in the freezer until you are ready to serve.
