Probably the most popular t-shirt quilt I do is sashed. Sashing refers to the strips of fabric that are sewn between the t-shirt squares. The little squares that divide the sashing are called cornerstones. After the sashing, cornerstones and t-shirt squares are all sewn together a border is added. The term backing is exactly what is says it is. It’s the fabric on the back side of the quilt. And finally, the batting is the cotton layer that goes between the backing and the quilt top. Once the three layers are quilted together on my longarm quilting machine, a narrow binding is added all the way around the quilt to close up the raw edges. There are several options for sashed quilts. One is to have the border and sashing the same fabric with accent cornerstones of a different color like the quilt pictured on the left. Another option is to use cornerstones to match the border and accent that with a different color sashing. That quilt is pictured on the right. If you choose one like the quilt on the right, you can also choose to have an extra inner border that matches the sashing like the one in the firefighter quilt pictured below. The price for sashed quilts is the same per t-shirt square regardless of whether you opt for accent cornerstones or accent sashing. If you choose to include an extra inner border, there is a $20 fee. I hope this helps to clarify some of the t-shirt quilt terminology and helps you to decide what style of sashed quilt you like best.
