A pojagi is a traditional Korean wrapping cloth. Some of these cloths were utilitarian and used frequently to carry household items. Others were special cloths which were used to give gifts or store valuable items or heirlooms.
Rotary cutters and rulers revolutionized quilting. Before they came on the scene, most quilters used templates and piecing by machine was challenging. Rotary cutters and rulers brought the chance to do st rip piecing, and made many patterns much more quick and easy.
Pin tucks are a nice way to add texture to sewing and quilting projects. They are basically small, parallel pleats of fabric pressed in the same direction with the piece then treated as a flat piece of fabric.
