The Japanese art of knitting or crocheting small, stuffed toys. Amigurumi is a popular technique in the world of crochet, originating from Japan. It involves creating small, stuffed yarn toys, typically in the form of animals or characters. The word “amigurumi” is a combination of the Japanese words “ami,” meaning crocheted or knitted, and “nuigurumi,” meaning stuffed doll. 


Blocking is an important step in the finishing process of a crochet project. It involves shaping and setting the finished piece by wetting or steaming it, then pinning it to a blocking board or mat while it dries. This helps to even out the stitches, relax the fibers, and give the project its final shape and drape. It is especially useful for projects that require precise measurements or have intricate stitch patterns.
