Thread Dye Question, Please Help!

[faerieangelchild]

Excuse me if I placed this in the wrong forum, let me know where I can go if that's the case.

I really need some help. I've spent two days searching for answers on the internet and for once, my savvy search engine talent has failed me. I'm planning on dying a linen dress I have in a tea bath, but first, I need to make changes which means I need to sew it. To make a long story short, considering the construction of the dress and such and such, I simply have to sew it before I can dye it in a tea bath.

I know polyester thread doesn't take on dyes very well, so I searched around and found this thread that was marked 100% glaced cotton. Some research into this taught me that glaced cotton thread is cotton that's been treated with a wax. That's all I know though.

My big, important, burning question is will this glaced cotton thread take on the tea bath dye along with the fabric?

Please help me, discuss, educate me. I'm dying (pun intended) to get this dress done and I will send you all happy wishes and thoughts if I can get an answer!

I don't know for certain, but I doubt it.  I know waxed, linen thread will not take up dye.  Have you bought the thread already?  If so you can make a small bundle and try to dye it.

I remember having a hard time finding pure cotten thread myself, but I know that both Gütermann and Mölnlycke sell them (the two most common threads around here).  If your craftstore sells them they might be able to order some inn for you?

I think you'll have to get plain cotton thread. Pretty sure that mercerized is just another word for waxed, and like Kara B said, I'm pretty sure that the wax will interfere.

Another option is to buy your favourite polyester thread in the colour you intend to get with your dye bath. That way you won't have to worry about whether the thread will dye or not.
