Basting is the process of temporarily sewing or glueing fabric together. This can be done by hand (on the right) or by machine (on the left side of heart) or with washable adhesive (turned under edges of heart). Quilters use basting to temporarily position applique pieces. They also baste the top, batting, and backing together before quilting.
Quilt basting helps position fabric before permanently sewing. Quilters use basting when appliqueing and when securing the quilt sandwich.
