thanks, i have tried to do tutorials before and they always turn out bad ,just not good at it. it is just $3 great stuff foam (walmart )put in a skull mold (target store) one can made 5 large skulls , so the cost was .60 cents a skull
I have never had problems with great stuff (except when I used a expired can ) this may have been what happened to you.
you can't rush the foam 24 hr to dry (don't poke the foam 5 min after you pour it to see if it's dry , i hate when I do that
cold weather effects the cure
one layer at a time and let dry (don't make the foam to deep keep it below 9'')
