A pair of breeches requires about 1 yard of coating weight wool, sturdy silk, cotton velvet or corduroy, or linen. The waistband, pocket bags & knees require 1/4 yard linen. Some fabrics such as corduroy have a grain that will require more yardage to keep the grain running in the correct direction. All yardages are only suggestions & are at your discretion.
Notions required include a spool of 35/2 linen thread or 50/3 linen thread to match & 1 spool silk buttonhole twist or quilters thread for buttonholes. You’ll also need 12, 5/8″ buttons & 2 1″ buttons. If you decide to add buttons to the pockets as well add another 6, 1″ buttons. And finally, you can add a second, 1″ button to each skirt so that the greatcoat can have anywhere from 12 to 26, 1″ buttons.
