Not sure what a "spoil" is, but it's possible we're talking about different things. Bottom Line thread is designed specifically for quilting, piecing, and appliqué. There may very well be pre-wound bobbins for embroidery also, I'm not into embroidery so I can't say for sure. Bottom Line is 60 wt and very strong.
eta: I just figured out you meant "spool". Well, I use Bottom Line both on my bobbin and on a cone, so that solves THAT problem!
