Same here, never been a problem--so far.

I have never paid attention to the grain of fabric when quilting, cutting large pieces, small pieces or paper piecing and it has not been a problem for me....uh oh, is that the quilt, oh good, passed Me by again.

I say do what you want.

I cut it up without looking and have done so for 15 yrs..it works out without a problem

Never experienced any problems! Done lots of scrappy quilts!

What is string piecing? I also have to learn paper piecing.

Thanks, I won't worry about the grain or bias anymore.

i use up my scraps all the time...have never paid any attention to such things as bias edges...have lots of them in fact since i save all those little corner triangles i cut off...still very usable. and when i fussy cut the left over swiss-cheese piece of fabric is stripped-cut into usable pieces...if i was making a dress/skirt that had to hang a certain way i'd worry about grain lines...making quilts? i don't worry about such things
my grandmother made fabulous wonderful quilts i don't think she ever bought a yard of fabric for one...she recycled...used what was too worn out to wear anymore and made quilts...she would not have been able to accomplish any of her beautiful award winning quilts if she had worried about grain-lines and bias edges

string piecing is what you do with all those narrow strips you cut off your fabric when squaring up or trimming...usually (but not always) strips less than 2" are used up. an example...if you wanted to make a 12 1/2" block...start with 13" square of muslin, place one of your strips diagnally across the center of the block...right side up. place a second strip over the first one right sides together, stitch a seam line down one side through everything, flip it open press, add next strip...keep going, when one side is all done turn it and place strips the same way the other side... when the square is covered with strips press well, square to 12 1/2" and you have your first string block done.

That's how a lot of people years ago made quilts--out of used clothing. That's what I used to make my first quilt. My mother who knew very little about quilting taught me how. We used old scraps of leftover fabris from the dresses she had made. She told me to cut out a square of cardboard for the template and the cut out scraps of fabric and sew together. She knew how to make a quilt but never made one. She did not know how to sew.
