Old wedding favors
Keep the most sentimental and important ones and then throw the rest out. The deflated balloons from the reception are probably a safe bet to throw out.
Christmas cards (yours and others)
Keep the last two years, if that. There’s really no need to keep Christmas cards after April, but it’s your call.
Forgotten holiday décor
Do you have Christmas elves that you always forget to put out every year? Just donate them and save yourself the hassle!
Old party supplies
If the party supplies come in any color or themes that remind you of the 70s or are too juvenile, use up all of the leftover plates and utensils at your next dinner. That way they aren’t just sitting around collecting dust!
