Hello and welcome from SW Iowa. Glad to have you here. I don't prewash.

Nice to have you here! I prewash red and black..then wash again when the quilt is done and use color catchers.

pre washing is your choice. I do because the chemicals on the fabric make my hands break out. I also do it to make sure nothing is going to bleed when the quilt is complete. And yes some Quilt shop fabric does bleed!

Hi from Ohio! Yes I wash all my material first.
This tip came from Kaye Wood newsletter

Tips From Our Readers....
I have taken a lot of classes over the years and heard teachers give their reasons for washing and not washing cottons for quilts. My mom and grandmother always washed their fabrics so I just did the same. About 4 years ago I bought some fabric to make a quilt at a local shop and two weeks later I bought some other fabric to go with it at another local quilt store here in Cincinnati. Both pieces came out of the washer solid gray. Trust me they did not go in that way. I have sewn for 40 years and this is the first time I have ever seen that and both pieces were bought about two weeks apart. Both stores cheerfully took the pieces back and gave me my money. One store's representative said the bolt must have skipped the last step to seal the fabric color in. I don't know if it is true but I learned right there to always wash my fabric. Can you imagine if you made the quilt, washed it and had all these gray pieces in a your beautiful quilt. It would be ruined! Or even worse gave it away and they washed it.... Phyllis

I am not a pre-washer. Unless it is flannel. I always pre-wash flannel because it shrinks at different rates. Even fabrics in the same line.

Hi and Welcome from NC!

Welcome, waving from central Indiana USA

I'm reasonably new to quilting, however, I always prewash, dry and iron all the fabric I buy, even before storing it on the shelf. This way it's always ready to go whenever I'm inspired.

I always wash all my flannels, and especially all my dark colored batiks. Wouldn't be too happy if the colors bled into each other after the quilt was all done. Not Good!!

Hi and welcome from the sunny state of Florida!!
