I was inspired to make a small leaf face cloth with green cotton yarn. There are free patterns to use for making leaves on the web, see below.
I hate to follow directions, but the leaf is made with three knit stitches on the left and the right sides of the leaf and a stockinette stitch is in the center. Increase the stitches or decrease the stitches right before or after the three beginning or ending stitches. Make the leaf the shape you wish to have. I don't think both sides should be the same, especially when leaves come in all shapes and sizes.
The old fashioned grandma type soap is very bright white. Isn't it beautiful! May God Bless You and Yours! Dawnie
