This has a lot of potential. I’m seeing it as a statement/focal wall. I found some pics for inspo and a good design will make it feel not so “off”. Depending on how big the lip is in front of the fireplace, maybe a basket with blankets or a thin book/magazine rack. It’s all about balance, right, so I’d put one large art piece or a few staggered smaller art pieces on the left side of the mantel then maybe a long ceramic-esque statue on right side (the first thing that popped into my head was a shark statue, if you’re into the nautical theme).

I post accessories because it would matter as to your art.... https://www.etsy.com/listing/915171928/18x18-throw-pillow-cover-thick-linen?click_key=00a9f6202d0d370c94866a7792e57679f5864f1f%3A915171928&click_sum=13fd9e20&ref=internal_similar_listing_bot-6 -------------------------------------------------------------------------------------------------- https://www.etsy.com/listing/877047017/william-morris-throw-pillow-cover-morris?ref=listing_page_ad_row-5&pro=1&frs=1&listing_id=877047017&listing_slug=william-morris-throw-pillow-cover-morris&plkey=2181f9bb37e207d1eaef8b9df895fd763e6e75b4%3A877047017

Additional note: I was trying to go for “California casual” or “organic modern” styles

Need ideas how to decorate my fireplace mantle . I’m not gonna hang anything . I don’t want anything that distract from the stone . My wall is greybeige . I’m pulling in blue with accessories. Also should I put anything on the left side floor ? Thought about a basket with throws or maybe a round fabric cube to sit .
