You can either use a knife to cut
out a heart shape in the center
of each side
of your
soap geode and fill with red colored clear melt and pour
soap; you can place a heart embed from a small heart shaped
mold into the center
of your
soap geodes and pour clear melt and pour
soap around them; or you use a small heart cookie or knife to create a heart embed for the center
of your
soap geodes from a thin layer
of red dyed
soap.
