fabric always seems cosier.

Would go a classic navy and cream , with rich gold accents, like this pic but reverse the wall colour and lounge colour, and with your English lounge choice and decor, it would look refined and classy. The navy would go well with your grey/taupe carpet and the walls, and your window design would lend well to the old Victorian/English style. Just one idea to consider :)

Hi Anna, the wetsuit fabric is not suitable for another reason - it will be prone to make the foam moldy. Outdoors conditions can also breakdown a fabric as well as badly fade the colours, so ensure you choose a fabric rated for outdoor use, and even then some will be better suited for your purpose than others. There are plenty of outdoor fabrics out there of varying quality and price points. Factors such as the fibre, colouring process, quality of manufacturer etc all will affect the comfort and durability of the fabric. My services do include custom outdoor soft furnishing, so please do not hesitate to contact me if you require assistance with your project. All the best, Louise - Decoro Custom Interiors, Sydney
