If you don't notice the difference when you put it in your basket, you most definitely will when you get to the register. That crappy yarn is EXPENSIVE and not worth the price you pay for it.
I became really disgusted with HL after they took their fairly extensive yarn selection away. I complained about it via email and got a ridiculously stupid answer back. I've supported that store for years, but I hardly buy anything from them anymore. Well played, indeed, Hobby Lobby--you lost this customer!
