Hat Frames of Fabric
Much care, thought, and patience must be exercised in making the frame of any hat. It is the foundation upon which we build, and if poorly made no amount of work can cover it up later. A hat must be right every step of the way. The frame is the first step, and so the most important.
The simplest hat to make is the straight brim sailor with a square crown, covered with velvet. Such a model we will take up at first.
Sailor hat frame—
For convenience we will use the following dimensions: Width of brim, three inches; height of crown, three and one-half inches; length of crown tip, eight and one-half inches; width of crown tip, six and one-half inches, and headsize, twenty-four inches.
