I made these simple and colorful decorations for my room using a whole bunch of paint chips and a few cheap pictures frames, as inspired by various pictures scattered around Pinterest (such as these linked here, here, here, and here).
The in-progress mess
The materials I used were a large handful of paint chips (free, from Home Depot), double sided tape, some picture frames (found at the dollar store and Goodwill), scissors, and a rubber stamp and marker for the calendar. The 3 frames I bought in total cost about $5 and everything else I already owned or got for free!
For the calendar I cut out 35 squares (an additional row of 7 would probably make for a better calendar, but my frame isn't large enough-for reference it's about 12" by 15"). I used part of a rubber stamp and a black marker to stamp circles on to a corner of each square for the date. I used double sided tape to position all of the squares onto the cardboard backing that came with the frame, and used a dry erase marker to write the days and notes for a reusable monthly calendar.
The completed product! Since I didn't have enough room for another row, some months I will have to squish a couple of days in the same square (although for my purposes, this is fine by me).
I purchased the other two frames at the dollar store, and made each of them by first creating a template for the desired shape, and adjusting its size so that would fit well into the 8.5" x 11" frame. Then I simply cut as many pieces out as needed plus a few extra and then arranged them onto a piece of paper to play around with the design and color arrangement. I used double sided tape again and a ruler to keep the rows straight.
I use these two smaller frames to write notes and reminders to myself occasionally as well since writing on them with a whiteboard maker works equally as well as with the calendar. They were really fun and easy to make!
