There is nothing new in the concept of making different shapes like stars, butterflies and leaves using different crochet and knitting methods. The leaf patterns provide much scope for experiment to create unique leaf designs like a broad single leaf or a collection of small compound leaves. Although crochet leaf patterns are more common, there are plenty of knit ones too for expert and beginner knitters. Many of these patterns have different names along with completely different working procedures, letting you pick a unique pattern for each of your projects.
