I started by creating a template to use in Photoshop. Pretty simple. I'll upload links to these files so you can use them too. If you need them in a .jpeg format, you can send me your kids' names and I'll make the name and send it to you. For reference...I used the font "Pharmacy" for the charts, and the font "traveling typewriter" for the actual chores. Both fonts can be downloaded for free at www.dafont.com (I hate it when I love a font and can't use it because I don't know what it is and/or don't have it!) I also added an "Extra Chores" section that was not on the original. This is where my kids can get "money-making chores" instead of just the mundane make your bed kind of stuff.
Here is the link to all the templates. I am totally new to this and trying to use Dropbox for it, so let me know if it doesn't work and you can't actually download the file.
