This is croblock #15 - Mug in the Kiss interlocking blanket series. There are now 15 square patterns in this series.

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

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