This thread was very nice for my job, a badge design. Good color and sheen for what I wanted it to look like.

However, I used too heavy of a backing, and experienced many, many thread breaks. Took 3 hours to get it sewn out.
On the next shirt, i switched to a lightweight, cut away backing, and no problems at all.
This is on a moisture wicking shirt, and I'm hoping the design doesn"t pucker after use and washing.
I'll let you know.
