I think I read somewhere here something about vinegar in the rinse is that for color running?
I usually don't prewash but the more I get into it I think it is wise. My fabric is all price ranges so I don't want my quilts to come out the size of handkerchiefs when washed :roll:
My current project is red and white so any hints?

Mimi Sharon wrote in the flannel for backing thread:
I use the salt and cold water, too! Even red holds it's color so well. My husband won't wear new jeans until I was them at least twice in salt water. He doesn't know it's salt water, he thinks I'm magic in keeping new denim from fading on him...

Read that thread and see what you think. I haven't tried it myself, but I always prewash. In case bleeding is an issue or shrinkage, I catch it before my innocent victim I gave it to finds the problem.
Let us know what happens. :-)

what is the web :lol:

This one. Look at the index at the beginning of the forum here for flannel for batting.

Ruthie, if you haven't already sewn everything together, PREWASH! I no longer trust red in any way shape or form. It loves to betray us and turn everything a lovely shade of pink when we least expect it! If anybody can give us the perfect solution to colorfasting red, I'll be forever grateful.

Ok I have asked and I'm washing in salt rinsing in vinegar. then when I wash the whole thing I'll get a bleed sheet for the dryer. .. Wish me luck.........and thank you :D

I use Retayne that I buy at my local quilt store to set the dye. I like to sew with batiks and when I tried setting the dye with saltwater I had to do it over and over again.

I rinsed 4 times . the last 2 with vinegar........either it works well .or the excess is gone. If it ever bleeds pink and red is prettyLOL

I do only use good quality fabrics for quilting, but I nearly everything I quilt is in various shades of red and creams, and I never pre-wash. When I'm finished with my quilt, I toss it in the washer on regular cycle, warm water, with one of those color catcher sheets from Bounce. They work great, everytime!
