Introduction to the Jars Quilt Block
Bug Jar Quilt Block Patterns

This type of quilt block is often called a "bug jar," but you can fill it with anything you like.

Sew Bug Jar Quilt Blocks, Cookie Jars, Candy Jars & More

Most of the bug jar quilt block patterns I've seen depict tall, quart-sized canning jars. I wanted to design something a bit flattened, with more jar width to accommodate large prints.

The result... a jar in a square that looks a bit like an old fashioned pickle jar. Fill your jar quilt blocks with candy, flowers, bugs, cookies... any theme that suits your quilt.

Finished block size: 12" x 12"

Use any background you like. Black is pretty effective for many prints and can make the jar seem to pop out from the fabric, but another color might work better with your quilting fabrics.
