This is something I found to do on pinterest. I made one for me, one for my mom's birthday, and one for Kaila who is getting married! Now that they have officially been given their presents I can show off my handy work without spoiling a surprise.
I used velcro instead of working with messy magnetic paint as they did on pinterest and I think they look amazing! All the blogs I looked at said the clear calendar sheets were the hardest to find so if you want to make your own go to http://www.orientaltrading.com/api/search?Ntt=clear+acrylic+calendar because it is a WAY better deal. OR I will be making and selling these at the Farmer's Market this summer...in case anyone is interested.
