A response to:
So, i was always told that i need to prewash my fabric before i start a project, but a freind told me that she never pre-washes her fabric. So i am asking your opinion on the subject.
I never pre-wash unless it is some funky type fabric that might bleed color into the other fabrics. I used to spend hours pre-washing and pressing (ugh...) all my pieces before using or storing until I read an article from Fons & Porter. They explained how in the past, quilt fabrics were less stable in their weaves and quality, so pre-washing was a necessity to ensure no color bleeding and even washing and shrinking after your project was done. Now, fabrics are much better quality (at least those fabrics made by leading manufacturers), dyes are a lot more stable, and while their might me some shrinking, it's usually uniform and negligible. I think the exception would be flannels. I always preshrink flannels since they shrink so much more than regular cottons. Plus, it's so much nicer to cut fabric that is 'new' and crisp with a little starch!! And a quilt that shrinks up a little bit after washing is so pretty! It gives it a kind of antique look right off the bat!
( This is mostly a stab at crappy Wal-Mart fabric. Sorry if anyone uses it, but it really can not be compared to 'quilting fabric' from legit stores. I get mad when I see ladies scrambling to buy their $1-$2 dollar flannel to make into humanitarian blankets for little, sweet babies in foreign countries. Don't they know those blankets have to be washed on a rock for heck sake? Look at it sometime. It's woven like cheese cloth! You can see right through it!!) OK. Rant over.
Official advice: Pre-shrinking won't hurt, but it won't necessarily help anything either. If you get your groove on while ironing, go for it! If you have 20,000 other things to spend your time on, don't bother unless the specific fabric requires it, like flannels or wools that you want to felt.
