Have your child use a black marker to write a phrase, such as 'best grandpa ever,' on white paper and take a photo of it with your phone or camera.
Open the photo in Photoshop Elements or similar design software. Use the magic wand tool to remove the background.
Use the magic wand and the erase tool to remove all of the background from inside the letters and to clean up the image so that only the letters are left. Save the file to your computer in PNG format.
Upload the PNG file to an SVG converter site (I have used SVGCreator.com) then download the converted file. [If you use Cricut design space, you can skip this step.]
Upload your PNG or SVG file to Cricut Design Space software. Select 'simple.'
On the next screen, make sure to choose 'cut file' on the left, NOT print then cut.
Open the uploaded design in a new canvas. The design is now ready to be used for all of your personalizing projects!
