Temporary Tattoo's are readily available on ebay and other places, they are easy to apply and also easily removed with either soap and water or babyoil and make up wipes.
I've seen some excellent tattoos on your dolls over the time and always been well impressed, although I haven't ever got around to getting any or finding out anything about them myself.
You have done a brilliant job.
I did think I submitted this yesterday but it was still in a open tab on my phone this morning .
