One ward made super cute napkins for a Relief Society Meeting celebrating the birthday of Relief Society.
Using pinking shears, they cut out squares of white fabric, and with a marking pen, wrote the words on the fabric.
I think you could do this same thing with the Relief Society seal image. I would put the RS seal 25 or so times in a document in my word processor. Then I’d print it IN REVERSE on some iron-on transfer paper to make cute RS napkins with the seal on them.
