One of my friends pointed out that my earlier post made it sound a little as if only people who are planning on joining the Knit a Long can get Keys to the Castle for the discount price. That's not true!
Buy the Preview for the KAL through Ravelry at the lower price (before Nov. 1), and you will still get a full version of the pattern on Nov. 1, when the pattern is released. Get in early to save a little cash. :)
Also (and this is SO COOL), you can get 20% off your Perfectly Posh Sport yarn by entering the code “Castle-KAL” when you checkout at FiberWild! They’ve got every color available, either in house or as a special order color!
