Jason C. ★★★★★

The color is the exact reef blue I needed for a beach-themed quilt, and the 40wt weight runs smoothly through my machine without any fraying. Very happy with this purchase.

Julian ★★★★★

Finally, a thread that doesn’t snap mid-stitch—this cobalt runs smoothly through my machine and the 1000m spool lasted through a whole quilt top. The color is exactly like a tropical sea, which really pops on white fabric.

Mia G. ★★★★★

This reef blue is exactly the vibrant aqua I wanted for a beach-themed quilt, and the 1000M spool means I’m not swapping cones mid-project. Stitches lay flat with no fraying, even at higher speeds on my machine.
