1st gather all your tools and the cameo or the item of what you will be molding. this way you wont be side tracked.

get your clay ready, and press it out. depending on the item, determends how many layers you need,
or you can just roll a ball and use your hands. bout work nicely.

take the item and carefully press it in the clay and roll it if you have to. i do not have enough clay it this photo, but i hope the point in clear.

sorry another bad photo, but i hope the points there.
check your inprint for any major defects, then trim your mold if you wish,

bake according to your clay.

your should have something like this,
the left it one i did with my hands and is deeper, the left i pressed.
both work good.

get your clay ready and put it in to the mold as so. if you dont press hard engoug the image with be very light, too hard it wont wanna come out easy.

tah duh. check for flaw you dont want.

trim it.
i pefer blades.
and smooth it out.
my photo once again not the best.

then place on to another piece of clay.
in which ever way you want.
i normal use cookie cutters or cardstock cutout.

just add whatever you want, roses, gitter, jewels, etc. and you can change her hair style after trim.
sorry about the bad photos, but i hope you enjoy your fimo cameos and other molds.
