Embroidery Thread - Is It All the Same?

Not really. Most embroiders use either rayon or polyester thread for the upper thread in most embroidery applications. Embroiders will have their preference as to which type they use. Generally customers don’t need to be concerned about what type their embroider uses but there are some exceptions. For example, if you’re purchasing embroidered uniforms that will receive heavy laundering with bleach, then polyester thread is necessary. Another example would be if you’ve had trouble with embroidery thread “bleeding” such as a fill (area) of red thread, then polyester thread is a better choice.
