Dritz615-61 Invisible Thread, 150-Yards

I love it

A little hard to work with at first because it's impossible to see and the strings curl everywhere getting in the way, but once you get the hang of it, it works great. Perfect for hand sewing, don't know about sewing machines. Super thin, thinner than a fishing line, but very stretchy and very difficult to break which is awesome, actually haven't been able to break one yet even with aggressive pulling. Only downside is you need to work under a bright light or a lamp which makes it easier to see.***To the people getting frustrated finding where the string starts, this is just like a lot of other threads. You peel back the top sticker and the start of the string is wedged in the small cut at the rim. Then use a needle to pull out the wedged tip of the string. Not difficult to find at all once you know where to look.Also, another "tip", stretch out the fabric before you sew the end off. The string should "bubble" up a tiny bit and look a little weird, but if you don't do this and have the string lay completely flat, the ends will be too short and look crimped once you invert the fabric.Will definitely buy again because it works awesome for hand sewing and I'd rather buy this than collecting a bunch of different color threads.

Used to hem curtains. What else can I say about thread lol

On the plus side, it's truly invisible. I bought it to sew up some fabric that was both semi-sheer and had a gradient to it - it fades from a sky blue to a salmon pink to a pale yellow. Like a sunset.And it's certainly invisible against it!On the other hand.. it's a HUGE pain to work with. Obviously it's not your typical thread, it acts more like a fishing line.. and I was hand-sewing with a basic needle. Getting it in the eye of the needle, not a big deal, actually pretty easy with some good lighting. Knotting it? Oh.. my god. Every time I got it together in my hands to knot it, one side would slip away. I almost feel like knotting it every time took longer than sewing the individual pieces I was working on! LolOnce it's in and it's going, it's pretty strong! It got tangled a few times - not because I couldn't see it, but because it was difficult to control all of the excess while hand-sewing. But it all pretty much pulls through with a few tugs, since again, it's more like fishing line so it's smooth, almost plastic-like.

Love this!

Very handy

Sewing on multicolored trim it was a game changer for me. I was concerned that it would not sew easily through my machine, but it worked perfectly, so happy with the outcome. I love it and continue to use it.

This is a truly invisible thread! I sell tie-dye tshirts and love how it just takes on the colors of the tag and shirt. It's very strong too!
