Lampshades are a fabulous edition to add to your room which can be totally bespoke to your room/house. You could either use leftover fabric from other jobs or you can pick a new fabric which either coordinate with your room colours or bring a statement to the room. A range of sizes and shades can be made to order.
Bean Bags are a great accessory for a room, whether it's a family room, playroom or a bedroom. They can be made in a variety of fabrics depending on where and how they will be used. You can add detailing in the form of pockets and piping. All my beanbags are made with an inner lining. This helps if you need to wash the outer fabric at some point.
Changing the fabric on your seat pads is a quick way to freshen up your room without too much upheaval and cost. You can either use different fabrics, as shown in the picture, creating a more casual feel for a kitchen or you can have the same fabric creating a more formal feel for a dining room.
Doorstops are a fun and useful addition to any room. They can be functional to hold an annoying door or just there for decoration. They don't require much fabric at all, and a thicker fabric is better for longevity although most fabrics can be used.
