This is the first for me I did mitered borders and I am sure they are going to be wavy any suggestions???

Starch them well! If you have enough fabric to cut them lengthwise, it will help reduce the stretchiness.

When I do miters, I measure across the center of the top and mark that length on the border with pins. (I measure from the center out. Then I mark the 1/4" starting and stopping points on the top itself. When I attach the border to the top, I align the outside pins and pin those first. Then I ease the rest of the border evenly on the top. I sew from outside pin to outside pin and repeat with the neighboring side. Then I sew the miter. Never had a wavy one.

If you did them already, how about sharing a picture? That way, it would be easier to (maybe) see where you went wrong (if you did), and offer some helpful suggestions.

Thanks.

And, in the meantime, here's a Sharon Schamber video on mitering corners. She uses a block as an example for ease in showing the techniques, but it could apply to a king size quilt.

And even if you don't use every single one of her pointers, at least you'll know what you should be looking for, and how/what to fix it when you find it.

Okay here it is I tried fixing by borders but they are still wavy I am at the point it will have to do what do you think??? also finished log cabin tied.

First, I love the log cabin - the dark/like contrast is really striking.

OK, back to your borders. It does look like there is some fullness still in the borders.

Can you post a pic of the miter? While the miter looks flat, it doesn't quite look like it's at 90 degrees, so I'd like to see a close-up looking down on it (before I do anything drastic like suggesting you redo the borders). ;-)

The turquoise really works - gives the top a real sparkle.

Is this a gift, a throw for the den? What's the plan?

When I do borders, I sew up to 1/4" from the corner. Then I lay the corner out on the ironing board or table. I use my large 12"x12" cutting ruler and fold one side under to form the 45degree angle. Then I press it, carefully pin it and sew along the fold line. It works every time.

Good luck and let us know how your miter borders work out.

this is the best I can do

how did you measure/cut/sew the borders.

did you notice it is mostly the last border and they were sewn together than sewn to quilt. I know I did not measure correctly but I wanted extra for the miter guess I did not need that much. I also think my last fabric is more strechy But it is what it is I can't keep ripping on it
