Virtually all embroidery designs are digitized for 40 wt Rayon or 40 wt polyester (Poly Deco) thread. There are a few exceptions: Some are digitized for heavier threads, some for lighter threads, a few for metallics; but they are few and far between. Enlarge a design (without changing the stitch count) to use a heavier thread like Sulky 30 wt. Cottons or even 12 wt if the design is just an outline type (redwork) design. Decrease the design size (without changing the stitch count) and use a lighter weight thread like 50 wt Cotton+Steel or 60 wt PolyLite. But, first do a test stitchout when changing weights and/or sizes of a design. Always feel comfortable using 40 wt Rayon or Poly Deco.
