I have my own tiny knitted man that I made as a child, I take him most places with me and he even has his own blog, Knitted Man. Here he is in a yarn bomb he found on holiday.
My knitted man is quite big compared to some of the knitted items from Mochimochi Land. You can buy the patterns or choose from the free ones available on their blog and make your own. I love these tiny bunnies.
