When using the BeFunky Graphic Designer, you will notice the majority of the templates already have images, effects and graphics on them. Luckily, BeFunky also gives you the option to start from scratch with any template. Here's how to do this:
Step 1: Head into the Graphic Designer.
Step 2: Find the Templates tab, and select 'Social Media Graphics'.
Step 3: Select Twitter, and pick any pre-set template.
Step 4: Click the 'Reset' button on the bottom bar of your workspace. This will remove all the pre-existing template elements but keep the size and shape of the canvas in the same dimensions that you will use for Twitter. From there, begin adding your own design elements.
Step 1: Open the Graphic Designer.
Step 2: Click on 'Templates'.
Step 3: Select the green 'Custom Template' button.
Step 4: Size your custom template to : 1024px x 512px, and click 'Create'.
