This is croblock #4 - FatCat in the CATS interlocking blanket series. This is a 18”L x 16”W croblock, so it is larger than traditional sized blocks.

Croblocks can be used in blankets, throws, runners and clothing. I have used Lion Brand Mandala (mill ends)and Red Heart comfort yarn -black.

Skill level required for this pattern is a beginner with some basic knowledge of interlocking filet crochet
