As for the Hello Kitty cookie cutter, you can find one in ebay. At first, I was choosing items in a Japanese website, but it became expensive. Luckily my sister thought of ebay. She did a search and bought this. It came with a stencil if the effect you want is like my cookies. Using sprinkles the way I did was a b*tch! Sorry for my language, but it took so damn long. (Partly due to inexperience.
) Designing it with cocoa is faster. The second cookie cutter would also be great, especially if you want to design by icing. Works great without icing too. One day, I will get myself the cookie/bread/veggie cutter mould.
