This is a knit hat for dogs with ear holes. It's made durable and warm by using different counts of charcoal yarn and combining bulky yarns. The face and neck are ribbed, and the top of the head is jersey knit. To ensure a comfortable fit, it's made with soft, stretchy, and skin-friendly wool blend yarn, knitted with knitting needles. Although crocheted items can be made faster, they tend to be stiff and not very stretchy, so I've chosen to use knitting needles even though it takes more time. I've been making dog knit hats for 5 years, and I knit each stitch carefully, hoping your dog will stay cute and warm. ■ Size Face circumference: 34cm - 38cm Please measure the circumference of your dog's head, from the base of the ears on the forehead, under the chin, and around. ■ Materials Main body: Wool blend (100% wool and a combination of 70% wool and 30% acrylic) 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 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 hanging can cause stretching, remove excess water with a towel and dry flat. It will be shipped via Yu-Packet Post Mini. Please note that it will arrive flattened, but it will return to its original shape if you shake it lightly or steam it.
