Deborah Doherty generously provides most of her patterns for free. tee | 23 is my favourite design of her, but she has other designs that are absolutely beautiful.
Sari Nordlund is one of the most popular designers at the moment and her popularity is undoubtedly deserved. Louise pullover is not one of her most outstanding patterns, but it is still gorgeous and, moreover, it is free *wink, wink* and thus a great opportunity to get to know Sari's pattern writing style without having to pay for it.
Rachel Illsley is one of my most favourite designers and I cannot believe I have never included one of her patterns in eye-candy. Low Tide is probably my favourite pattern of hers, but her colourwork patterns are also outstanding. There is also a Low Tide Shawl which is equally gorgeous.
