To cover edge wire—All edge wire must be covered with crinoline or a cheap muslin. Cut a strip of such goods on a true bias, three-eighths of an inch wide. Remove the selvage and stretch the strip. Bind the edge wire with it, holding it very tight. Sew close to wire using a stab stitch.
Right side—wrong side—
This stitch is made by taking a long stitch on right side and then a short back stitch on wrong side. Lap ends of crinoline one-fourth inch at finish, but do not turn ends under.
Square crown—
A square crown is one having a flat top, or one only slightly rounded, with the sides slightly sloping in towards the top. A crown of this type three or three and one-half inches in height would be at least one and one-half inches smaller at the top than at the bottom. Any crown made separately from the brim must be large enough to cover the headsize wire on the brim at the base. To eliminate any slashes or seams in the side crown, a paper pattern should be made. Following paragraphs explain how this is done.
Pattern for slanting side crown—
Cut a piece of manila paper one-fourth inch wider than crown height and one-half inch longer than headsize wire measure. Slash across this paper in four equally distant places, within one-fourth inch of edge of bottom, then lap slashes at top a little more than one-fourth inch, or about enough to take out about one and one-half inches. Pin slashes. Lap ends of paper one-fourth inch and pin together. Place this pattern on brim with joining at back and pin to upturned slashes on brim. Try on to see if any alterations are necessary. It can be decided at this point and changes made should the crown be too sloping or too straight. An amateur should try on a frame often in order to be assured of lines and curves that are becoming. Remove pattern from brim and cut off from top and bottom any irregularities on the edge.
To cut side crown from buckram—
Remove the pins from the seam, allowing pins in slashes to remain. Lay pattern flat on smooth side of buckram, lengthwise of the material to take advantage of the natural roll. Cut close to pattern; lap the ends one-fourth inch. Sew, using a fine back stitch close to each edge; this makes two rows of stitching. Sew a piece of frame wire to top and bottom of side crown, keeping all joining at back. Use same method as in sewing edge wire on brim. Cover both wires with crinoline.
