It's hard to think up of creative design materials for businesses that have niche markets. Don't fret - Canva has a wide selection of medium rectangle (IAB) templates that you can easily customize to suit any kind of business need. Take this modern advertisement fit for websites that are about swimming, adventure and watersports, for example. It has a no-fail orange border featuring a fun photo of people boom netting. You may choose another photo from Canva's stock image selection or upload your own, do this by dragging and dropping it on the template or using our photo uploader.
