Before the introduction of the sewing machine in the 1870s plait hats (also called strip straw) were constructed by hand stitching. There were two main methods of hand stitching:
After the introduction of a sewing machine capable of stitching plait, and with the growth in size and number of factories, hand-sewing decreased and became more associated with model hats. Much of the factory work was undertaken by home workers who were supplied with a machine and received deliveries of work to be completed each week.
There were different types of machines, some only stitching straw as a flat sheet, or stitching from the brim in towards the crown. There were visible stitch machines, including a zigzag-stitch machine introduced in the 1920s and concealed stitch (box) machines. The Willcox and Gibbs 17-Guinea machine is the most well-known but the same chain stitch machines with similar configurations were made by other makers including Grossman and Singer.
With the introduction of ‘endless’ man-made fibres in the early 1900s, machine stitching increased in popularity. From the 1980s the introduction of sinamay fabric and cheaper hoods meant sewing skills began to die. New machinists were no longer trained and outworking decreased. As the industry declined in Luton and hat factories closed, many machines were disposed of or left in factories and the homes of outworkers. These are the ones that are now available.
New machines specifically designed to sew plait or braid into a hat are only available from China. The alternative source is to find an old machine and set it up with a motor or treadle and dedicated workbench. Many machines appear on selling sites but not all are suitable for stitching straw. Machines were used in hat manufacture to complete a wide range of production processes. Spares including needles are no longer available in the UK, the specialist machine repair companies having closed as the hat factories closed.
The process for a factory-based operation and millinery studio are very similar but will vary slightly according to the design and materials used.
A hat can be sewn on a flatbed domestic machine into panels which are then assembled into a design, however this was not the method used in wider production. Traditionally sewing the hat would start at the top centre of the hat crown (the button) and spiral outwards to form the crown and then the brim. According to some designs, gussets (gores) might be added to the shape and for other designs the hat was made with a double brim.

There are no training providers for straw hat making including sewing straw plait. There are a number of opportunities and short courses to learn hat blocking techniques with straw and sinamay.
Note: There are other milliners who are able to hand sew strip straw, but are not currently using the technique.
