Macybaby your "Oh my gosh" quilt is gorgeous! How long did it take to make this beauty?

Thanks everyone crisis averted I was wrong the bias is not on the outside such a relief! Hopefully will post a picture when it's complete.

Hope you can breathe more easily now - :)

A lovely quilt!

Try painter's tape
 

If you haven't started sewing yet, you can add some 2" painter's tape close to the bias edge on wrong side of the fabric. Don't sew on the tape but place it really close to your needle - I usually let my metal foot run on the tape. Just lay tape down on the fabric in one piece - you don't want to re-position it because of the stretch. The tape will help keep your edge from stretching and if you sew with a short stitch it should be fine.

Maybe you haven't see all those waves on some quilts. The longer the bias, the easier it is to distort it.
This quilt would have had bias on the entire outside edge. I'm glad she found that that was not going to happen.

Another solution if you are concerned about bias would be to put a narrow strip of stabilizer on the seam line. It can stay there and not be seen after the binding is on.

The crises has been averted, but I may have another solution for anyone else who might run up against this problem. You might put a thin strip of stabilizer near the edge. Use the kind you can sew through and it can stay in there and won't be seen.

maviskw, the quilt I posted a picture of has bias all around the outside edge, with rather large setting triangles.

I did a lot of sewing with tricot and other knits. Cotton on the bias is nothing compared to knits.
