This is a knit hat for dogs with ear holes. It features a two-block design using a mix of four strands of charcoal and black yarn, or a mix of mixed yarns. The combination of yarns makes it durable and warm. The face and neck are ribbed, and the crown is stockinette stitch. A string for size adjustment is included to prevent slippage. It's made with soft, stretchy, and skin-friendly wool blend yarn, knitted with knitting needles for a comfortable fit. Although crochet hats can be made faster, they tend to be stiff and not very stretchy, so I chose to use knitting needles even though it takes more time. The face and neck are ribbed, and the crown 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 the ears on the forehead, around under the chin. ■Materials Main body: Wool blend (70% wool, 30% acrylic blend) Pom-pom: Wool blend acrylic Please note that this is a handmade item and is not perfect like commercially available products. While I knit each one carefully, there may be some loose thread ends 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 it stretches when hung, 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.
