Is a cut at any angle considered a bias cut
 

If I cut a piece of fabric at any angle other than the straight of grain, will I get equal stretch? In other words if I cut something at a 60 degree angle, will the fabric stretch just as much as a 45 degree cut?
I'm working on a twister quilt and wondered about the outside edge of the quilt once I'm done.
I've worked with quilts that have had large HST on the outer edge and .... well ....you know. :o)
Thanks!

I believe the amount of stretch you get will differ depending on the angle that is cut. But anything cut not on the straight of grain can stretch.

I would think that yes, any cut not on the straight of grain is cut on the bias.

Some woven fabrics also stretch on the grain - most usually stretch more on the cross grain (from selvage to selvage) than on the lengthwise grain.

In most cases, the true bias (45 degree angle) has the most stretch.

The 'same' amount of stretch--no. But you will get 'some' stretch. Best idea would be to put that piece of fabric on the bottom so that your feed dogs would compensate.

Avoiding full bias, which is 45 degree angle to straight-of-grain, helps a little. A 60-degree bias cut will not stretch quite as much as a 45-degree bias cut, but will still stretch considerably more than a straight-of-grain cut. If you heavily starch the fabric before cutting, this will help stabilize the fabric so bias edges are less likely to stretch out of shape while you are working.

Thank you ladies for your input.
I was hoping to hear that a cut at 45 degrees has the greatest stretch.
I'll be able to manage this project a bit more easily.
So much knowledge on this board. :>)

A cut at 45 degrees *does* have the most stretch. Absolutely. Assuming we are only talking about quilting cottons, because the rules can be different for things like knits with spandex, etc.

And I'm not just saying that because its what you want to hear, 'cause I'm #notayesman.

I'd say anything other than the straight would be a bias but depending on how deep the cut is would determine how much stretch.
