I saw a version of this on Pinterest (see here) - What a fantastic idea!
I wanted something a little sturdier and bigger, so I went "shopping" on eBay. I found a Longaberger basket/liner/protector for under $30 that was perfect for it! Could I have found something cheaper? Maybe, but I wanted something that wouldn't fall apart years from now and I can even hang it if I want to.
To incorporate some type of cross stitching, I cheated and used pictures from my old yearly calendar! I used ones that I knew I would never make and that matched the month. I then glued them to a background and then to cardstock to make it firmer.
I wanted something bigger than the regular index card, so I bought the larger ones instead. And go figure, the stamp that I could have used for the date was donated a while back because I never used it!
And just so you know, this project was Ming approved!
