I leave selvedges on, and I'm a pre-washer. So my stash is full of pre-washed fabrics with selvedges intact. I trim them off when I'm cutting fabric for a quilt, but that means I rarely have long selvedges, just lots of little shorties. I throw them into my crazy quilt bin.

I also leave mine on until I'm cutting the fabric for a project - then I just do a little snip at the end right below the selvage and rip it - it comes off straight every time. I save it - comes in handy when tying bundles, etc. But I like the idea of keeping it for rag rugs.

I always remove the selvages and now I am cutting them 1.5 inches wide and saving to make a string quilt.

It's interesting that most quilters feel selvages must be removed, but other quilters save them and make entire quilts out of them. I remove them because I think most of them are ugly. I'd leave one if I were certain it would be in a seam allowance and I needed the extra fabric.

I cut mine off and tonight I had to cut one off because it was woven so tightly that it distorted the fabric print that I needed to use. After cutting, a quick touch of the iron and the fabric laid the way it was supposed to.

I leave mt selvage on until I HAVE to cut it off, that way I know where the straight of grain is and when I cut it off I leave a bit of the actual fabric on it...someday I'll make one of those selvage quilts, ya just never know.
