Need yarn advice

I found this sweater that I absolutely must knit. It calls for mercerized cotton. I just bought this (super soft) Caron acrylic worsted today (right before I went to the library and found the pattern in a book :wink: ), and I would love to use it, but…
What do you think? Should I risk it, or should I go out and buy some sport weight cotton?
Any advice is greatly appreciated.
:thinking:

Worsted is twice the thickness of sport, so I don’t think it’ll work unless you want the sweater to be ginormous.

Thanks, Ingrid. I guess I’ll go out and buy the thick stuff.

I hope you mean thin stuff. Sport is thin, worsted is thicker.
