Isacord 1000m Polyester 5335 Swamp Thread

I’ve been using this 5335 Swamp thread for dense fill stitches, and the polyester holds up beautifully without any fraying or snapping. It’s nearly twice as strong as the rayon I used before, with a noticeably smoother run through the needle.

The thread runs through my machine like butter, and the 1000m spool means I'm not constantly swapping out for a new one mid-design. The color depth on this swamp green is perfect for nature-themed pieces, and it holds up to multiple passes without shredding.

I’ve been using this for my latest project and the tension stayed perfect even on tricky fabrics. The strength is noticeably better than rayon—no breaks or fraying issues at all.
