Did you go to the NEC a few years age when the knitted quilt was there? It was a quilt so to be in the show must have had 3 layers. It looked as if it hd. Been hand quilted down the seams of the knitted blocks. I thought about putting a crochet quilt in but due to health problems had to stop. My plan was to crochet a top on blocks then find a batting which I could dry and would hold its colour, if this did not work dye muslin or something similar to show through the gaps in crochet. Then backing and finally try to quilt in the seams . In my head it worked.
