Dear Riri, Thank you for your patience. The hat is now complete, so please take a look. As always, we prioritize the finish of the front side during sewing, so some unevenness in the seams may occur on the back side (e.g., image 12). Since this time we used patterned fabric, it may be somewhat noticeable even on the back side. I made it carefully, but I couldn't get it perfectly even no matter how many times I tried. I would appreciate it if you could understand this as an individual difference due to being handmade, but please feel free to cancel if you are concerned. 【Size】 A: From forehead to behind the ear 6-9 cm B: Up to 35.5 cm (made it a little longer) C: OK if 2.8 cm or more (5.5 cm or more if A is the smallest size) D: 17.5-22.3 cm E: 7.5 cm (made it a little longer this time, considering the dog breed) Hand wash & ironable (be careful with high heat on decorations) If you are satisfied, I will list it for 1299 yen. Please comment when you have time. Thank you. ⚠ Please read before purchasing ・Because of the stiff texture, strong creases may not return to their original shape.
