Four Square block

Four Square potholder calculator

A Pattern and calculator to make potholders using the Four Square quilt block in a variety of sizes and quantities. Fabric requirements and instructions are from a few common fabric sizes. To do the calculations, javascript must be enabled, otherwise the pattern is for a pair of 8-1/2 inch potholders. While every effort is made to be sure of accuracy, I am unable to test every variation. Before you cut up large amounts of fabric, cut and sew a test block or two. If you find any errors, please email me at "jeannethro2 at yahoo dot com".
