DIY Cable sleeves, where can I buy.......

Hello there DIY gurus, trying to pretty up my Powercord.
Where can I buy beautiful sleeves or expandable braided sleeves to cover my DIY Powercord...

Looking for example the fancy blue and green type from MOON AUDIO or something in that type, not ordinary expandable bright colors...looking for a variety. Not for commercial use but for personal use only

Thanks
