The simplest shaped brim is the mushroom style.
To make pattern for brim—
Make a paper pattern the same as for the straight brim sailor. Measure the same for the headsize wire, join ends of wire, shape to fit the head, and pin on paper pattern of any desired width. To make the brim droop, slash the pattern from the edge to the headsize wire in four different places equally distant. Lap these slashes one-fourth inch at the edge, and pin. The pattern may also be slashed in eight or more different places if desired, the slashes being adjusted by lapping more or less according to the amount of droop which may be becoming.
After the pattern is adjusted satisfactorily, mark with a pencil all around just inside the headsize wire. Remove the wire and cut the paper on this line. Cut pattern in two at back and lay out flat on smooth side of buckram, leaving pins in slashes. Cut close to outside edge and allow one-fourth inch for the lap at ends. Mark on buckram with pencil close to headsize line and cut one-half inch inside this mark. Lap ends one-fourth inch and backstitch closely at each edge of flap. Sew a strip of crinoline flat over seam to smooth it up. Sew headsize wire on place marked, which will be one-half inch from inside edge. Keep all joinings at back. Slash buckram from inside edge to headsize wire every half inch. Wire edge of brim and cover wire with crinoline—same method as used on sailor brim.
To cover a mushroom-shaped brim—
If not very drooping, it may be covered without making a seam in the material. To do this, begin by placing the corner of the fabric on top at the front of the brim. Pin the front, back, and each side, always pulling with the thread of the material, and pin closely at edge, with pins at right angles to the brim. If covered with georgette, satin or silk, which is pliable, the fullness may all be worked out without a seam. Baste close to headsize wire and finish edge by following same method as used in finishing sailor brim. Also follow same method with facing. If the material used is not pliable, or if the brim is too drooping to admit of stretching the material smoothly, a seam must be made at the back. The method would be the same as used in covering the rolled brim.
In covering with anything as sheer as georgette, it is advisable to line with some other material first. The color could be made deeper by using a lining of the same color, or made paler by lining with white. The lining should be fitted and sewed on with the outside material.
