Stitch in the ditch certainly isn't the only option for quilting, but what will work in this instance will depend on the piecing pattern, and your taste, and how much time you want to put into the work.
Tying a quilt is certainly an option, and I've seen some wonderful tied quilts (vintage and modern). I'd recommend that you just google "tying a quilt" or "how to tie a quilt," and you're sure to come across some good tutorials.
I hope this helps!
