I offer machine stitched and hand tied quilts. Both are lovely on a quilt.
The hand tied quilts are done using embroidery floss with colors to match the background of each knot. Hand tying is really easier on the shirts because it does not puncture the fabric as many times as the stitching. This is especially important on older, more fragile shirts.
The machine stitching is more modern looking and does not have the hand made look. Each graphic is individually outlined with machine stitching.
