Last year, I posted about advent calendars. I love our tradition of hanging our advent calendar and alternating days where we fill it for each other. Ours looks like this. I adore the version I posted about before from Terrain and the newer verison they have where the pouches hang from a grain sack; however, I've seen a number of options that you make yourself.
The latest issue of Martha Stewart Living showed a super simple version made of different sized envelopes that hang from the wall. Paper-Source would be an excellent source for envelopes (or MS suggests Paper Presentation). Online, Martha also suggests hanging paper treat bags from a string or ribbon with clothespins. Etsy has a ton of cute paper treat bags (e.g., chevron stripes, a mix of patterns on kraft paper, polka dots, and regular stripes) and also decorative clothespins. Image credit to Martha Stewart.
Another take on using clothespins for an advent calendar is pictured below courtsey of Visual Heart. If you don't want to paint clothespins yourself, definitely check out Etsy (I plan to use decorative clothespins to hang our Christmas cards this year so I ordered some of these already). Head over to Visual Heart for instructions and image credit also to Visual Heart.
Finally, an option that is a bit more complicated but certainly a kid-pleaser is the piñata advent calendar! Instructions to make this awesome calendar can be found on Handmade Charlotte. I can only imagine how excited kids would be to break open a piñata every day leading up to Christmas. All images credit to Handmade Charlotte.
