Okay,

So first of all I have NO idea about fabric and what cutting on the bias is compared to cutting salvage to salvage.

However when I was looking for "How to Quilt" videos I came across this video for doing binding, and was wondering if I could cut the same way for 2 1/2 inch strips for a Yule Log quilt. Just to keep the cutting down to a minimum? What are your thoughts?

Here is the Link:

Cutting on the bias makes the strips have more stretch. This is especially good for scalloped borders and such. If you wanted to do an entire quilt with bias strips, you would need to be mindful of the stretch. Things could get weird.

Ahh I see...sound like it might be better to do it the regular old way. :)

Quilters seldom cut strips on the bias. Really stretchy pieces. Better to cut quilt pieces selvedge to selvedge.
Bias stripes are used for curves. Making applique strips or binding a scallped edged quilt. When binding a straight edged quilt you still use strips cut selvedge to selvedge

I wouldn't recommend it. As noted in the above posts, bias strips would be very stretchy to sew together. It could make your quilt end up looking misshapen.

I agree.

I avoid bias strips like the plague LOL When I have to cut triangles I starch the fabric stiff to keep the stretching to a minimum. It doesn't take much handling, and the edges of the bias cuts want to start rippling...
Straight cuts going selvage to selvage or running parallel to the selvage are your best bet :D:D:D

Often, I will cut my borders first cutting along the selvage side, usually I can get longer strips this way. Then I cut out my pieces :wink:
