Examples of pairing your event with awareness months:

Example 1: Your business is celebrating its 25th Anniversary in April. Try pairing your event with World Habitat Awareness Month. Raising funds for a local ocean preservation organization, like 5Gyres, would be a great idea. You could create a online fundraising store hosted by Ethix to offer earth-friendly drinkware, such as reusable aluminum canteens, and custom-printed, recycled or organic t-shirts for sale, and share it on your social media pages, in your newsletters, and on your website.
Example 2: Your union local has its annual Labor Day parade coming up. Pair this with the month-long Library Card Signup effort in September, and invest in some union made stickers and buttons to hand out at the parade, encouraging kids to sign up for a free library card. You could also create specially-designed union made kids library tote bags with your union logo on them (and even better, get them union printed with a union bug!) to hand out at the local library to children who signed up.
