to create anvil you must have:
3 blocks of iron (27 iron ingots to make)
4 iron ingots
the blocks go in the top three spaces, whilst the iron ingots go on the bottom three spaces with one ingot in the middle

bam you got anvil, now you can tame a horse and call him Joergen whilst you tame a wolf and name him Sven
or you can enchant your items whatever
