With any true indigo fabric, there’s a risk of color transfer, where a little blue makes its way to light-colored fabrics or your skin. This is called crocking, and it usually comes out in the washing machine or the shower, respectively! It’s inherent to natural indigo dye, and it’s part of what makes those garments fade so beautifully. Still, for the first few wears, we recommend laundering separately and staying away from light-colored upholstery.
Pro tip: the first time you light a candle, let it burn for 2-3 hours, or until the whole surface is liquid. Wax has muscle memory, and this trains it to burn evenly and last as long as possible. You'll also want to get in the habit of trimming the wick to 1/4" before lighting to prevent tunneling and excessive smoking.
