Brighten up a bookcase
Cover the backing of a bookcase with adhesive contact paper, fabric, wallpaper or scrapbooking paper. If you don't want to make the design permanent, apply your chosen backing material to a heavy weight poster board and cut to size for each shelf and insert into the back of the bookcase.
Build a small device charging station
Pick up a small, basic DIY ledge shelf and cut some slits or drill holes in it for cords to run through. Mount on the wall above a powerpoint. No more cluttered countertops and what a great way to keep track of the family's devices.
Replace a window shade
If the window treatment above your kitchen sink is looking a little worse for wear thanks to cooking splashes and spills, replace it with an and inexpensive fabric. Pick up end of roll pieces for just a few dollars from fabric stores.
Try your hand at a fun paint technique
Update tired flooring with a custom rug. Using a vinyl floor remnant and paint, you can create a fun, personalized focal point. Varying the stripe widths creates a cool, casual look. Or create a striped or geometric feature wall.
Recaulk the bathroom
Old caulk can cause serious damage by leaking water. If the caulk in your bathroom is mouldy, discoloured, or it's cracked, you need to remove it and start again - cleaning the space well, and replacing it with a new layer.
Maximise storage space
If floor space is limited in areas like your garage, study, entryway, etc, add hanging storage to make use of unused walls and ceilings. This is especially handy for seasonal items such as ski gear and things that take up lots of room, including bikes.
