This is Patch Abilities' collection of 12 Valdani COLORFAST machine weight 35 threads. These are the 12 most used threads in her quilting tools.
Colors are VARIEGATED so each color's been dyed using several shades of the color. For instance, red contains bright red, dark red, dull red, medium red...all on one spool. This makes these colors blend well and pop nicely on any shade of fabric color.
You can use these to machine blanket stitch on cotton or wool. The thread weight is heavier (thicker) than standard sewing thread (usually 50 weight or higher), so don't use it to sew seams but DO use it to applique stitch on any project.
Colors included are: H207 darkened blue, M43 vibrant reds, M81 backyard honeycomb, O126 old cottage grey, 5 ecru, P6 rusted orange, P12 brown, O511 black sea, O178 tea dyed stone, JP12 seaside, O562 horizon storm, O560 morning grass.
