1.25" Finished Thangles
Thangles are sold by the finished size and that means the size AFTER the quilt is sewn together. For example, 3” Thangles will make a half square triangle that measures 3 ½” square before it is sewn into the quilt and 3” after. Another way to think of it is that the raw or unfinished size equals the finished size PLUS ½” for the seam allowances.
