Looks like this version of DWR is square blocks? If so, you can FMQ quilt in sections. There are many different ways to do this, but here is one. Join all the blocks for your top. Cut a strip of batting about 1/3 the width of your top. Cut a strip of backing at least 4" wider than your batting strip. Lay the backing down, then the batting, then carefully center your quilt top on the batting. Pin/spray/glue baste this section as usual. Quilt your pattern, make sure you stay a couple inches away from the edges of the batting. When the center is done, cut a piece of backing that will go from the other piece to a couple inches past the end of your top and seam it to the original piece. Cut a strip of batting and butt (don't overlap) it up against the original piece and whip stitch. Pin/spray/glue baste this section as usual and quilt. Repeat for the last section. This way you are only dealing with the maximum of about 1/3 of the quilt in your machine harp at a time.
