I will make a liberated quilt, but it's really not on purpose. See, we had this tub from my great aunt, and in it I found several items: a few crochet quilts, some rectangles of shirt fabric that was being sewn together in a quilt, and a rather long giant rectangle of almost canvas material that had been sewn together as the start of a quilt. The seams are all cock-eyed and intersections a mess, but rather than take all the fabric apart and start over, I've decided to cut it into smaller pieces, preserving all those crooked and awful seams in the quilt. My new seams will be perfect, but it will also preserve the old. I did the same with the shirt rectangles, and from it emerged a quilt that keeps the posterity of the original process.
I think that is what people are trying to replicate- times before rotary cutters and modern rulers and tools. The shirt pieces were paper pieced- it had small segments of paper still attached into the stitching, and I was almost tempted to leave them in the quilt, but I had to wash the fabric and they dissolved.
If by liberated quilting they are relishing wonky seams, I am not sure I agree with purposely making those errors on new quilts, but where I run into ones from old quilts, I celebrate them.
