This is a knit hat for dogs with ear holes. It is made durable and warm by knitting with four strands of yarn held together. The face and neck are ribbed, and the top of the head is stockinette stitch. To ensure a comfortable fit, it is made with soft, stretchy, and skin-friendly wool blend yarn, knitted with knitting needles. Although crocheted items can be made quickly, they are stiff and don't stretch well, so I chose to use knitting needles even though it takes more time. The face and neck are ribbed, and the top of the head is stockinette stitch. I've been making knit hats for dogs for 5 years, and I knit each stitch carefully, hoping your dog will be cute and warm. ■Size Face circumference: 32cm-36cm Please measure the circumference of your dog's head, from the base of one ear, across the forehead, under the chin, and back to the starting point. ■Materials Main body: 100% wool Pom-pom: Wool blend acrylic As this is a handmade item, it is not perfect like commercially available products. Each item is carefully knitted, but there may be some loose ends of yarn or slight irregularities in the stitch pattern. Knit products may unravel or tear if pulled strongly or subjected to impact. Please hand wash in lukewarm water and avoid wringing. Since hanging can cause stretching, remove excess water with a towel and dry flat. It will be shipped via Yu-Packet Post Mini. It will arrive flattened, but please understand that it will return to its original shape if you shake it gently or steam it.
