Well, I was browsing around in facebook this morning and having a look at some of the groups related to knitting. In one of the groups I came across this blog http://knit-harry-potter.blogspot.com and was blown away at the content. There are links to free patterns that people have posted for you to to knit anything from a bookmark to full sweaters. Some of the patterns are well worth a look. I highly recommend spending time at this blog and it's links for all Potter fans.
The balaclava and hooded gloves pictured here are not, however linked to the above mentioned blog. This was a custom knit I did for a fan of both Harry Potter and friends and of balaclavas. I think I shall keep this one to myself for now.
