Whether you’re into paper crafting or quilting, you’ll find this square ruler to be indispensable. Paper crafters can use 4.5” for half-square triangles and small paper piercing. Quilters can use it as a template for 4? squares, baby quilts and more. The 6.5” can be used to square up corners of blocks, for marking and cutting patchwork and miniature quilts or photos and mats. Use the 9” as a template for squaring up blocks, borders and backgrounds and for cutting squares, triangles and strips. The 12” and 16” is great for fashioning scrapbook and album pages, making templates for pillow tops and for simple square patchwork designs and cutting larger pieces.
