I read on some forum, maybe this one, you can buy a liquid thingy?? to put a drop on a spool of thread to help it not be so knotty. I'm working on some hexegons. I seem to have lots of coates thread & every other spool seems to really knot up. Is there something I can use to prevent this. I have tried other brands much the same thing. I've tossed a couple spools but that gets costly. LOL. I will never stock up on sale thread again. I think it must be out dated. Does that even happen

Don't know about the liquid, but is it possible that you are threading your needle with the wrong end of the thread? Make sure you put the thread in the needle as it comes off the spool, not the cut end. Also, after I thread my needle, I smooth the thread between my fingers all the way to the end about 3 times BEFORE I put the knot in. It can also be that your thread is too long. Try using a shorter piece (12" or so)

My mom uses a bit of wax on her sewing thread.

Yep. It's called Sewer's Aid. Here's a pic and description of it: http://columbiariverquilting.com/sewers_aid.html I especially like this stuff to use on the thread for hand sewing. It really does seem to keep it from tangling as much. I used to use bee's wax (like my mom taught me), but I like this even better.

There is a liquid silcone stuff for on cones of thread on longarm quilting machines. You can buy a solid silicone called "Thread Heaven" that works really well to keep knotting and tangles to a minimum.

Make sure you thread your needle with the end that comes off the spool. The other thing that helps is to put your thumb on the thread where it goes into the fabric.

I take a dryer sheet and fold it in hafe and run the dryer sheet
all the way down the needle and thread it works wonderfully. :D

half I meant to say..lol

Are you thinking of sewers aid? I get it at Joanns. I use it on my thread sometimes. When I do stippling and I start to have skipped stitches I put a drop on the thread and it stops the skipped stitches.
I first used it on older thread I had that gave me trouble while sewing. A drop on the spool and the bobbin thread helped me.

Wow, that was fast. Yes, it was sewers aid I had read about. I will look for it at Joannes when we go to Yuma next month. We are Snow birds & I'm getting my list of things I want to try. Need to get several boxes of those color catchers for my friends. Maybe some on-line shopping (free shipping). I will for sure be going to Fabric Depot.
PS What's that new to me Feedback 0% thingy under our user name.

I'm going to try using dryer sheets! Thanks for the tip!

I use beeswax when I'm handquilting to keep thread from tangling. A little goes a long way.
