I use Presencia 60 weight, 3 ply in Winter White or Amost Grey for almost all my machine piecing. For hand piecing, I use Presencia 50 weight, 3 ply. I pick quilting thread depending on the project, but fr machine quilting, I usually use either YLI monofilament or DMC 50/2 cotton embroidery thread. For hand quilting, I usually use Gutterman hand quilting thread. For applique, I prefer Mettler Silk Finish 50/2 or 60/2 or monofilament. For hand applique, I use YLI silk thread.
