I have made several so far... [SEP] [[VIDEOID:d8f0b04ede522646e3e02a3470175a04]] I just winged it, so don’t know if you half fill the mold then make two to fit together (if possible) or if you just “dome it” making a coat on the back of the comb you made filling the whole mold, so the back side is rounded, not flat. I haven’t seen instructions on how to, as no instructions were included. (Maybe Youtube or Google it to know.)
