Finding the right categories
Scroll down to "Marketing Materials" and choose " Poster" or "Poster (US)".
Quick tip: to find the most suitable layout, give both categories a try and you might be surprised at how many layout options there are. The only difference between these two is their sizes, which can always be changed later on.
Or you can search for "Poster" in the search bar, which will give out results from both Poster and Poster (US). I personally find this easier to choose a layout.
By clicking "Edit this design", you're now ready to go!
Choose/ change a layout
If you want to change to another layout, scroll down the layout menu on the left. Click the one you like and drag them toward the editing space.
