QAYG with mitered borders
 

I'm doing quilt as you go on a quilt and would like to put on mitered borders. Is anyone aware of a tutorial that shows how that is done? I'm thinking you would not want to include the batting in the diagonal seam at the corner and have no idea how I would deal with the backing on the border. If it is impossible I'll have to send the quilt to a long armer.

Treat your border as one piece i.e. miter the corners for both the front and the back then attach to the body of the quilt. Finicky but it can be done.

This will be quite the challenge. I don't know of any tutorial to help you out. One thing for sure I want to see this quilt when it is finished with its mitered corners. I always do my borders straight across when doing QAYG.

I've not been able to find a tutorial for mitered (quilt as you go) borders but I have to say that your quilt is beautiful. What pattern did you use? I love the colors & the black sashing.

You would miter the batting just like you did the border fabric. Cut the edges of the batting on a 45 degree angle. Use wash a way seam tape to hold the edges together. I put the tape on both sides when I use it.

Your quilt is beautiful!

Here is another thought.

If you are at the outside edges of the quilt, do you really need QAYG technique? You no longer have to attach more blocks. You are finished with QAYG.

Miter the front border fabrics in the corner.

Miter the back border fabrics n the corner.

Miter tape the batting corners.

Smooth the layers and quilt.

If you want to miter multiple borders, you sew all the borders together for one border and miter them all at one time not individually.

In my mind, I can see this working. Am I missing something?

The quilt is called Urban Patchwork from the Jason Yentner Urban Jungle pattern book. Using the In the Beginning Urban Jungle fabric line.

I think I can envision how to do it using Ronda K's hints. Miter both the front and back borders without any batting involved. Then slide in a strip of batting on each side, zig zag it to attach it to the batting for the main quilt top and then quilt it, one side at a time. The border batting need not be mitered. You could do the sides first and then the top and bottom. I'm strongly tempted to just send it out for quilting, especially as my machine started acting up.

Beautiful, beautiful quilt, Quilting Chris! I love the color choices. And my, oh my! That was a lot of piecing for a QAYG!
