This will save you a lot of time and money, and is a step in the process you should never skip. Most swatches are free, and if not free, very inexpensive. Having a range of fabric samples will give you a sense of quality, durability, color and texture all lending to the overall aesthetic you’re trying to create within your space. Some hues are not what they seem online- maybe you think you’re getting true orange, but it’s actually a rust color, and some shades will look different in your space, because of lighting, which makes a HUGE difference. It is definitely worth spending $10 on swatches than being saddled with a $3000 couch in the wrong color.
