Nice work + I'm looking forward to some autistic tech wizard reconstructing your face from the small portions visible through the holes.
My grandmother used to have these spread across the kitchen table for the last twenty years of her life.. I grew up in her jumpers as well.
Very nice. My wife crochets but only hats and baby blankets. I don't think she would attempt a rug.
Its about 140 x 140 cm, triple crochet stitches. Basically a big granny square :)
