This book is excellent if you're new to knitting (or an impatient knitter like me), the patterns are simple and the jumpers knit up fast. There are patterns for polo neck jumpers, cardigans, hoodies and even fancy patterned jumpers for the more experienced knitter. The book also contains some basic patterns for people, so you and your dog can have matching outfits! The only downside would be that the book claims to have 30 projects, I noticed some of them are just the same jumper decorated with different things, like diamontes or pom-poms.
I have already had many requests for the jumpers I've knitted and the dogs look adorable when they are wearing them!
