Thirtysomething Square Up Tool - Gaylee Quilting, Gayle Bong Quilting Tool at Work

The magic of Thirtysomething is all the angles in a unit are the same! Simply cut rectangles diagonally, match the angles and sew. Then use the tool to Square Up the units. It is designed to trim units to finish 3" or 4”. Try the basic technique with this free pattern "All Wound Up".

For pattern books with quilts designed using the Thirtysomething Square Up tool see:


Thirtysomething, too! 

In 2013 two lines were added to the tool to make the Square Up tool double as a cutaway template for making companion pieces to the Thirtysomething unit. For detailed instructions and dozens of new blocks see The Thirtysomething Block Book.
