Hat Blocks Australia team Darryll and Renee Osborne recommend this very popular High Arch Duchess block. It features a soft duck tail and a deep curved arched base. As it is not a head fit but the high arch allows the shape to perch firmly on either side of the wearers head, to give a jaunty appeal. Measurements are 7.5cm long and 6.5cm wide. If you have any Block questions contact Darryll or Renee for their expert advice.
