Smith is also available as part of the collection Whimsical Little Knits Book 2
Smith is an adorable Hedgehog that can be knit in a variety of sizes by using different yarn weights. Although knitting anything with spikes is going to be a little fiddly, the construction method used is simple and fun. The body is worked in the round and the spikes are worked in seperate pieces and joined to the body as you go, this also makes it easy to work the spikes in a darker colour if desired. Smith was inspired by one of my favourite childhood books, Smith the Lonely Hedgehog by Althea.
In addition to the yarn and needles listed you will also need toy stuffing.
