When you get a really bad cold, bad enough to stay in bed for a few days, you'll have time to work on you big crochet blanket.
The cats will cheer you on and keep you company while you do another row between coughs.
When the cold turns into bronchitis, you'll have time to crochet three or four rounds around the edges. The cat will be so impressed.
When all's said and done, you'll have a nice blanket to lay with on the couch while binge watching episodes of Lark Rise to Candleford on Netflix.
