I may not be going back to school this September but I do expect to spend more time working indoors as the weather cools off. That said, I'm not ready to give up on summer either - not just yet. My books could definitely use some sprucing up, so I made these paint splatter bookcovers:
It's a perfect activity to do outdoors, and preferable too unless your walls are in need of a drastic paint treatment.
Materials you will need: plastic bag, rocks, paint brush, bowl, acrylic paint, and grocery bags or kraft paper.
Step 1: Protect your work surface, spread out the grocery bag, and weigh down with rocks.
Step 2: Water down the acrylic paint if necessary (consistency: it should be on the verge of dripping off the brush) and flick your wrist to splatter the paint. Allow each colour to dry before applying the next colour.
Step 3: Cut a rectangle around your book that is at least 6" longer in width and at least 4" longer in height. Fold the top and bottom down to book size, and fold the sides around the book edges to cover.
You could even splatter paint onto items like pencils, rulers, and bookbags. It would be a fun way to personalize school supplies for someone who is heading off to class.
