Insufferable Know-It-All is the next project in a series that honors my favorite wizard school books and movies and makes a great gift for all ages. Its design lends itself well to many different styles of décor and allows you to display your fandom using something besides house colors and cartoonish images that might better be displayed in a child’s bedroom or rumpus room. This solid granny square lapghan works up quickly and its pattern can be repeated to make your finished product as large as you need. As pictured, the finished size (with one pattern repeat) measures approximately 40 inches square.
