Hello!! I recently moved into a new place and would love some help picking out a rug to go with my set up. Also would love help understanding how to properly size the rug. Does it need to fully fit under the couch? I would assume it doesn't need to go under my TV stand but maybe touching it?
I'm going for a mid century modern look. I would love to change my couch eventually but am stuck with it for a bit while I focus on purchasing other furniture first. I'm thinking an olive green couch but welcome any suggestions. :)
I'm not afraid of color. I want my space to feel cozy and match well.
Thank you for any help :)
