I was first introduced to Cosmo Embroidery Floss about 10 years ago when I signed up for a Frosted Pumpkin StitcheryStitch-Along. Back then, the Frosted Pumpkins had all their stitch charts in Cosmo colors. I had only ever stitched with DMC (or whatever brand was on the floss bobbins of thread boxes I had picked up at yard sales & thrift shops), so I was intrigued to try a new brand of thread. Once I started stitching with Cosmo, I never went back and I've spent the last 10 years transitioning my thread collection to Cosmo floss.
The first thing that I noticed about Cosmo was how soft the thread feels in your hands. I spend a fair amount of my free time hand stitching, so having a thread that is nice to hold is pretty important. Cosmo uses only the highest quality extra-long staple cotton in the production of their threads to create a cotton floss that is known for its soft texture and durability.
The second thing that sets Cosmo floss apart is the vivid, almost silk-like luster of the thread. The full range of 501 solid colors (plus an additional 140 variegated colors) has this signature sheen that produces vibrant stitch work. All Cosmo floss is colorfast and fade resistant as well.
