Women's Cardigan with Embroidered Flowers and Gathered Waist

I made this cardigan in the late 1960s or early 1970s and cannot find the pattern source.  The yarn is likely Red Heart or something similar from the period in a worsted weight.  Small pink and green flowers are embroidered along the top of the gathered waist, the top of the three-inch ribbing on the puffed long sleeve, along the button band, and over the top of the ribbing going over the shoulders.
