Crochet Maths
This is a very dumb question but here goes...
If 2 balls of yarn makes a crochet blanket 75cm × 75cm, how big a blanket will 5 balls of yarn make?
Blanket is not from a pattern so I can't go by that. I'm doing 4 rounds moss stitch, 1 round double moss (double crochet, chain 1), and repeat (starting from a magic circle & 1 single crochet, chain 2, 1 single crochet, chain 2, etc as the 1st round).
Yarn is Athena Jewels Quartz in shade Agate, DK weight (100g = 300m), using a 6mm hook for drape.
