This is one of my most popular beanie hats that I sell at farmers' markets and craft shows here on the central coast of California. I hand knitted the hat with 100% acrylic yarn. Hand wash in cold or warm with mild soap, gently wring out, and air dry. You can machine wash these fibers on the gentle cycle in a garment bag and then air dry, but I strongly recommend hand washing for a longer lasting hat. This beanie hat is available in four sizes: These sizes are approximate age ranges. Small - fits 1 month to 6 months, $21.99 Medium - fits 6 months to 2 years, $23.99 Large - fits 2 years to 10 years or petite adult, $25.99 Adult - fits average adult $27.99 SHIPPING IS FREE FOR THIS ITEM!
