First pick some clip art that fits your needs - we always run to the grocery store for milk and bread, always. So those definitely made the cut. Now if you're computer savy you can place them all just so to save you a step - I didn't want to put that much thought into it. Next outline your box - mine was a cute heart, but rectangles are probably more practical from a layout persepective.
Then cut everything out. See, if you had arranged things just so, you wouldn't have to cut out all the clip art individually, but it works. Then glue them on where you want them. Note, I picked especially bright and cheery clipart, only to find out that my color printer was out of ink - of course. So you can use your color imaginations.
To protect it from grubby hands and seal the cutouts down, I covered it in contact paper. I have a love-hate relationship with contact paper. I find the best way is to set your item face-down so there are no wrinkles on the important side. Then fold the back over onto itself and slowly press towards the seam. After pressing all around, trim off all the excess contact paper.
Alright, let's move on to the markers. I used buttons but there are so many options. I just traced the buttons onto a self-adhesive magnetic strip (leftover from HERE) and cut out the circles. Then peeled them and stuck them to the back of the buttons - easy.
That's it - now you're ready to grab your children and head to the store in confidence!! Cross your fingers that they will be so focused on marking things off their list that they won't even whine about having to run errands...
