family reunion preparation

Hi friends, I am preparing square muslin blocks for my family to put their handprints on and their signature,
and then I will create a quilt or table-cloth with the squares.
need an idea how to do this.
one idea is to trace their handprint with sharpie...?
one idea is to use acrylic paint on their hands, and they press their hands onto the square cloths. and then later, I paint the handprints with Textile medium to make them permanent.

what have you done with this idea.?

thanks,
Carol Sue
