What is the average width of Sashing on a quilt?
Sashing Width and Length
Work with sashing that finishes at one-fourth of the block’s width, or less. That means you would use sashing up to 3 inches wide (finished) for a 12-inch (finished) quilt block.
What size should Sashing be?
Quilt sashings can be narrow or wide, ranging in any width desired from 1” finished (or even smaller for mini quilts) to several inches in width. Sashings should generally be proportional to the size of the blocks — you can effectively use a wider sashing with bigger blocks.
Should quilt Sashing be cut crosswise or lengthwise?
A: Although you might think you’re saving fabric by cutting across the grain (from selvage to selvage), it’s best to cut lengthwise. When you cut crosswise, the fabric edge will have a little more stretch.
