Anyone use this product? Is it already pre-shrunk? Any need to pre-wash it?

is it a poly/cotton blend? or is it 100% cotton?
if it is cotton it might shrink a little bit= like any 100% cotton- if it's a poly blend it probably will not shrink.
if you normally pre-wash- no reason to stop now- if you do not normally pre-wash- no reason to start now-
it is a personal choice to pre=wash your fabrics
no difference here

It's the only muslin I buy, and i buy a bold whenever I run out - from Jo-Ann's on sale. I wash as I use: I cut a piece several inches bigger than I need, serge the edges and wash and dry - using hot water - at least 3 times. I want it to get ALL it's shrinking done before i use it! It still needs pressing, but it doesn't wad up into a mess like regular muslin. Tip: serge the ends together, and it won't twist up in the dryer.

I'm a pre-washer. Many others on the Board are not, so you'll get both kinds of advice. It's pretty much up to you. I've found that muslin shrinks much more than other cotton fabrics. That's why I prewash it 3 times.

I bought some Roc-Lon muslin - said it was pre-shrunk on the end of the bolt.

I'm glad I didn't believe what it said. It shrank a LOT! - but that may be because I also soaked it in hot water before washing it.

Thanks for the info! I usually pre wash; guess I won't be changing my ways with this fabric

I use 100% Cotton Permanent Press Muslin from Walmart and never prewash it and it does not shrink because Iwash In cold water.
