This is a knit hat for dogs with ear holes. It's made with a light gray and off-white yarn, using four strands held together to create a durable and warm fabric. The face and neck are ribbed, and the crown is stockinette stitch. A size-adjustment string is included to prevent slippage. To ensure a comfortable fit, it's made with a soft, stretchy, and skin-friendly wool blend, knitted with straight needles. While crochet hats are faster to make, they tend to be stiff and less stretchy, so I've chosen to use straight needles even though it takes more time. The face and neck are ribbed, and the crown is stockinette stitch. I've been making dog knit hats for 5 years, and I knit each one carefully, hoping your dog will stay warm and cute. ■Size Face circumference: 32cm - 36cm Please measure your dog's face circumference, from the base of one ear, across the forehead, under the chin, and back to the starting point. ■Materials Main body: Wool blend (70% wool, 30% acrylic, held together) Pom-pom: Wool blend acrylic Please note that this is a handmade item and is not perfect like commercially produced goods.
