One of the three recent corgi patterns I created; there are two other corgis available in separate patterns.

You will need 1 skein of each yarn color. You will also need the following items:

2 6mm round brown safety eyes
1 6x8mm triangle nose/dog nose
a tapestry needle
stuffing

If you cannot find a 3mm crochet hook you can use a US D (3.25mm) hook; however, you will need to take more care to tighten your gauge. As with most amigurumi, matching the specified gauge is not crucial, just keep the fabric tight.
