Our seamless (no visible stitching/bulky seams inside) knotted baby hats were designed with comfort in mind! Constructed from two layers of a beautiful organic cotton and bamboo blended knit fabric. These are slightly thicker and a touch warmer than our bamboo baby beanies with a little bit less stretch! Can be worn rolled up for a more fitted look or down for a more modern and slouchy style -or as your baby's head grows. Fits most from Newborn up to 3ish months (4-6 months on average). Measures approximately 12" circumference and stretches comfortably up to about 14-15". CARE INSTRUCTIONS:Machine wash (woohoo!) on gentle cycle in cold water with similar colours. We recommend using phosphate free detergent to help prevent fading over time. Tumble dry low heat. To minimize shrinkage, hang or lay flat to dry. Iron on low heat (NO STEAM) if desired.NOTE: All items are handmade, so no two items are truly identical which is what makes each pair unique. Please be sure to allow for slight variances from what is shown in the photos. Pattern placement may differ due to the nature of our business. Colours may vary slightly from monitor to monitor.
