I have a bias ruler, it has a point on the end that you line up with your fabric and cut, cut, cut. Then I trim the ends and sew them on an angle...It worked for me.

I think the advantage is that you don't have to sew a bunch of seams. The beauty of quilting is that you can do it which ever way works best for you.

The tube method is supposed to be less wasteful. I've done it both ways. My first quilt (avatar) was a McCall's pattern & it gave a paper pattern for the tube that was so super easy to follow, but trying to do it without the paper pattern is more aggravating to me than the wasted fabric I tend to have when I just sew end to end.

I've used the tube method a few times and always found it counter-intuitive but less seams to join. The last time I needed bias I just cut the strips and joined them, I found it to be faster and I don't really notice the seams anyway.

I've done it both ways, but usually stick with sewing strips together.

I did it the tube method and found I made the tube too big for the amount I needed. Since then used the diagonal cut and join until I get to my length.

I found the tube method more bother than it was worse, yes you save fabric, but too time consuming and annoying, I just cut the traditional way.

I love the tube method. It uses every bit of fabric in the square/rectangle without having to sew a jillion tiny seams. I'd much rather sew 2 long seams and draw a few lines and cut by hand than sew a whole bunch of 2.xx" seams.

However, if I'm using a striped fabric for binding I do cut and sew a bunch of 2.xx" seams because I don't want seams going more than one direction and I want to be able to control it more.

i am also a fan of "the tubey method" for all the reasons mentioned.
i also like the fact that i can make so much binding with less effort and in less time.

i have never bothered to draw all those stupid lines.
it takes too long.
it's impossible to get the lines straight and perfectly parallel.
cutting with scissors, it's unlikely i'll get a nice, clean cut from one end to the other.
it is completely unnecessary.

once the offset tube is made, i use my rotary ruler and cutter to make the loooooooong bias snake.
although i have done it using my 24" ruler, i find it easier to keep the tube in position using either a 12" or 18" ruler.
less fiddling with the tube means getting done sooner, even though i use the shorter ruler.

I usually starch the section of fabric, just use rulers and start cutting strips as long as possible. I am not a big fan of binding but sometimes it just what the quilt needs!
