Currently I am working on my husband waistcoat, the pattern I use is Laughing Moon's # 109 Men's single and double breasted frock coats with two vests, view B.
The front will be from bottle green wool, the back and lining from black cotton. The clasp and black buttons are original victorian.
Maybe I'll do some piping, in black satin, like on this original black wool vest from the 1880's, which I found here,Woodland Farms Vintage
