Website and Facebook banner design

I have a handmade knitwear business and I would like to create a banner for my website and FB page. The idea is to show people wearing summer knitwear such as knitted bags, summer hats, swimwear, tops etc either at the beach or in a summer background with the knitwear highlighted in colour. Feel free to visit my website (www.lumiknitwear.com) to have a look at my products and my current banner.
Please feel free to reach out to me if you have any questions.
