These beautiful wedding blankets are actually capes that are worn by a bride on her wedding day. The blankets are handmade by the relatives of a bride and can take the family weeks to make. They are worn lengthways and attached with 2 ties around her shoulders. Your wedding blanket may have the two ties still attached.
The vintage blankets come from the Imazighen (their true name) and are made of wool and cotton. They classically have fluffy fringes running through them and are adorned with lots of sequins or traditional Kilim fabric.
They are considered good luck and kept to ward off evil spirits and provide fertility for the bride and her nuptials. They are stunning at the end of a bed, hung on the wall, and make a wonderful wedding gif.
