I used 5 inch square snack baggies, but I made the bag topper in two sizes, the second for standard sandwich bags because they are commonly found. I printed on regular paper and stapled it to the bag to keep the project simple. Cardstock or other papers of your choice could be used. I bought Christmas M & M's and separated the green from the red because the Grinch himself is green. After I printed, I cut the paper in half (there are two prints per piece of paper) and then folded the design in half before cutting so that the edges would be even. Because I used regular paper, I could see through the paper to line up the edges of the design.

Grinch Pills Bag Topper 2
Here is the same topper, but with a different poem. I stapled over the words! I thought about re-doing it for this example, but I remember how others say they like to see my mistakes so they can avoid them, so here it is!
