Care instructions are included with each bonnet, and we recommend caring for your bonnet according to its specific instructions. For most linen and cotton bonnets, we recommend hand washing gently using cold water, and tumble dry on low or lay flat to dry. They may be machine washed on delicate at your discretion; we recommend a mesh laundry bag for extra protection in the machine. Do not use bleach or oxidizing agents. Wool and some specialty bonnets (such as those embellished with beading or embroidery) are recommended for dry cleaning or spot cleaning only. Iron with a bit of steam as needed to release wrinkles and reshape your bonnet. We recommend pressing the underside of the brim on Brimmed bonnets to release any creases from shipping or storing.
