This hat is inspired by my favorite ceiling in the Harem Apartments at the Topkapi Palace in Istanbul. The dome was unusual in that it was completely covered in painted vines, with heavy 'ribbing' that was not apparent in other domes I saw, either at the Topkapi or elsewhere in Istanbul.
My interpretation is hand painted ivy on linen, with braided yarn cords along the seams to replicate the ribbing on the original dome. The button at the top will be different with every hat. It is fully lined and finished with an unadorned padded cuff.
