Easiest way to quilt this?
 

Thanks for ideas. I only have a pfaff expression 3.2 machine. The quilt is large 64" x 80" and I've never made one this big. I need help.

Easiest way?? Send it out to a longarmer. But that is not necessarily the most economical way. It is a pretty quilt.

well straight stitching does well and you can do that easily enough. going diagonally through the centers of squares. both directions. you can skip every other row if necessary. depends on batting instructions too how far apart. Your quilt will turn out great. no worries.

You only need to be concerned about HALF of the quilt under the throat at any time since quilting is done from the center out. Check out Ann Peterson's class on Craftsy about Big Projects on a DSM (not sure of the exact title). This size is easily manageable. You can do this!

This one screams continuous curves to me... It was actually like the 2nd design after straight and stippling that I did on my domestic.....You can follow lines so that you aren't turning the quilt that often which can help with the harp space issue.

if your machine has a serpentine stitch, that makes nice quilting. i adjust mine to as wide as possible and stitch length of about 3.0

I would do just FMQ, large meander or something like that. The straight line stitching seems like it takes longer than I like. Just me.

Divide your quilt into 4 sections. You can stabilize the quilt first by stitching in the ditch with a plus sign. Keeping the bulk of the quilt to the left, quilt your one section at a time with the easiest design you can do. Good luck!

I second the diagonal cross hatching. Would go nicely with the pattern. I personally would big stitch hand quilt it. It actually goes fairly quickly.
