My inspiration came from this photo.
I purchased the MINI muffin tin at Walmart for under $5.00. I then used my 2 5/16 Scalloped punch to punch the Christmas Paper Shapes.
I punched the numbers using the same template that I created for the RACK project. You can find a link to download that HERE (you will only need to use the numbers 1-24 from this sheet)After printing the numbers out, I punched them out using my one inch punch. I use the black circles as a guideline and cut right up to the edge of it.
As you can see in this next picture, the punch then centers nicely to punch out your numbers.
I then glued the numbers to the Christmas paper.
On the back of them I used magnets that I just cut from a roll of adhesive magnets. You can find this in the Walmart craft area. Here are pictures...they tell the story much better! :)
However, there are lots of links full of inspiration on the internet. Here are a few. You can also do a Google search for Muffin Tin Advent and find a lot of stuff that way too!!
