Install your doodlebat like you would install any font. And open your cutting software. I use Make-the-Cut. Type what you want in your text box, sometimes with the doodlebats I just type every letter.
Your images should show up on your virtual mat. I then split the images after. In MTC, you right click>shape magic>split. The images will then split apart so you can work with them individually. Some images may need minor adjustments for ideal cutting, but others will be able to cut as is! I wanted to use the phrase do the mash, but I obviously you can't use the stitch marks, so just pull the circle out and then I resized larger.
For my card I used the DB Lil' Pumpkins. I brought it into MTC the same way I did with the Frank's Friends Doodlebat above using the type tool. I resized the image and I copied and pasted a second image.
