My mom made a lot of these tops in the 1970’s.  Now there is a pattern called the “Angel Top”.  All my mom did was to cut  1 yard of fabric in a circle, then a circle for the head, hemmed the rough edges and sew a line down each side for arm holes, simple, right?
I bet you can do it.  I think I will try it today to get the sewing juices flowing.
Have a great day.
