I was just doing a google search on casting molds for bjd's and came across this site... well started reading and had to comment ... I've just finished the sculpting part of my second bjd doll ... I used the air dry paperclay to make her and has taken me about 5 months on and off. ... But I did in the beginning search out info about what was the best to make her out of either polymer or air dry paperclay... I chose the paper clay as it's so strong... I don't know how many times I bounced limbs off the floor with no ill effects LOL... It also can be baked in the oven for those like myself that just don't have patience enough to wait while it dries naturally LOL
But if you are going to use polymers you can use cloth limbs stuffed with polyfil as your core...once baked you can then remove the stuffing and then the fabric... if that doesn't appeal then you can use brass piping which you wouldn't need to remove... hope I've not sounded the know all ... just had to share what I've learned so far
)) ... can't wait to see some pics when you girls get going !!!
