Chequered cardigan in one piece crochet woven

To the fiiin I show you how it is that I make this checked cardigan worked in one piece... every row of fabrics is 10 to 12 minutes so calculating it is 228 hours that means about 8 to 10 days to make it.
Excuse me for taking so long, as you know I'm ill in health and so I'm too late.
MATERIALS:
6 balls and/or twine balls each 100gramos for a size M
