This is my tutorial on how to make your dog a wizard! :-)
So, here we go.
Step 1: Open Pixlr Editor
Then upload your picture.
Step 2: Lasso tool
Step 3: Background
Then look for some pumpkin pic! And use the lasso tool to cut it out.
And then, paste it.
Step 5: Add some decorations!
When you're done save the image.
Step 6: Pixlr Express (optional)
Upload your picture.
I changed the color a little bit with Anne effect.
Step 7: Add stickers and text!
Now she looks like a wizard hey!
You can add text if you want to, of course.
Add a border and you're done!
