I use the flip-and-sew method and make a row at a time of the quilt. I used this many times on T-shirt quilts. I make a strip a time with sashing between blocks and then quilt the strip. Add sashing and the next strip. And then quilt. I use batting that need to be quilted with the larger spacing. I made a DWR and pieced together the top which would fit the bed, 60 x 80 I think. I then quilted it by machine using my walking foot and outlined the arcs and corner squares. I did a FMQ design in the center. This size was easy to handle with my machine. I then did the "hang-down" on the three sides. I FMQ in them and couched a fuzzy green yarn (stitching through the batting and baking for quilting) to resemble a vine and added some small flower things on the vine. It was manageable since I was working on the edges. I also used this method on my avatar to the left of this post.
