i have been using blend of cotton/polyester thread. i ran out of the spool and put a new spool on and sewed some pieces together before i realized that it is 100% cotton. my bobbin thread still has the blended thread. i know that the cotton thread shrinks. is this going to be a big problem if i keep using this thread with or without the bobbin being mixed? and should i make sure that i am using all of the same thread on the project. so i guess should i take out what i have done and get some of the same thread that i started with?

Unless you are doing machine quilting (where it actually shows), I wouldn't worry about it.

i'm with Cathe. if you're getting nice stitches and good tension, don't rock the boat. i doubt seriously the cotton thread will shrink anyway (unless it's older than i am. :wink: )

And we KNOW that is REALLY old!

what? you've never heard of jet skis? :wink: :lol:

They don't go UNDER the water! ;)

I have heard that the polyester in the thread can cut or break the cotton thread. I don't know how true this is but polyester isn't a natural product. I've never mixed in my quilts or other sewing.
