Welcome to the forum!!! And beware - I too started with small Obitsu but eventually I ended up with big obitsu and resin - it is not a joke that we refer to the dolls as addictions LOL.
As you like making things for dolls you might seriously look at the larger 50 - 60 cm obitsu one day - they are a joy to work with and on and in some ways less, cost wise, to the resin
