As I browsed the site I was inspired to shoot this idea out there on designing your own nipples.
GATHER REFERENCE PHOTOS.:The First step is to find reference photos of the ones you like. (make sure they are fairly decent quality and clear in details if possible) Also make sure that at least one of the nipples is facing forward as you'll need this angle to create a scukpt template featuring the overall diameter and shape that the nipple has.
CREATING SCULPT ON TEMPLATE : The second step is to use a photo editing program to create a template with. ( I use photo shop) you could also simply crop the image measured in centimeters (3,4,5, etc.). You'll be placing clay on this and using it as a guide to sculpt/ copy the forward facing nipple. Then print it out on printer paper.(My example below).
SCULPTING THE NIPPLE: You only need to do one unless you're feeling adventurous!
(AS A SIDE NOTE: ISOPROPYL MYRISTATE STEP IS USED FOR OIL BASED CLAYS *SUCH AS MONSTER CLAY* (FEATURED) ONLY.
Tip: using very small sowing needles during the whirl pool step will result in very fine wrinkle details.(press semi firmly when making)
MOLDING THE NIPPLE:
PREPARING NIPPLE PIGMENT + CASTING SILICONE:
"POWDER PAINTING" YOUR NIPPLE:
UPGRADING YOUR EXISTING DOLL: THE BENEFIT OF HAVING A DOLL ALREADY IS THAT YOU CAN SCULPT THE NIPPLE AND HAVE AN IDEA OF WHAT YOU'LL END UP WITH WHILE DOING SO! RATHER THAN HAVING A TEMPLATE YOU WOULD SIMPLY SCULPT USING YOUR DOLLS BODY AND CREATE THE DESIRED LOOK USING THAT. once done follw the rest of the steps above.
*PUFFY NIPPLES*: after step 6 see texturing in above sculpting tutorials for some ideas on how to texture.
A couple of final notes:
A CURRENTLY UNTESTED TPE WORK AROUND: cut a piece of double sided tape to the exact size of the silicone nipple diameter and place it on the bottom of the nipple (perhaps it will secure and also act as a barrier between the two materials.)
A NOTE FOR CASTING THIS ADD ON NIPPLE: During the step where you pour the silicone in your mold have ready prior to that a rough sculpted nipple with areola that is roughly the same size as your dolls current nipple. Once you pour the silicone in the mold simply line up the clay sculpted nipple/areola to where you want the new cast nipple/areola to rest on top of. Then press it into the freshly poured silicone and leave it to cure. (some silicone will displace out of the mold so make sure you have mold release on the entire mold (outside included). Once the piece is cured and "painted" you should be able to slap it on your doll!
