You will be relieved to know that my recent bout of yarn-lust didn't result in a purchase. Maybe, as Amy suggested, it was the time between receiving Lidl's email and actually visiting a branch (Lidl is a supermarket chain from Germany), that allowed it to wear off. Maybe it was because I'd spent several hours rummaging through the stash on Sunday, reacquainting myself with what I already have. Maybe it was because none of the patterns are screaming "Make me in this!", but when I popped into Lidl yesterday, I was underwhelmed by the look of the yarn and the colours on offer.
It was all quite "Meh" in the flesh. Ok, but nothing special. Even the sock yarn didn't appeal. Forget the bargain price. Cheap is no good unless you want to knit with it. And I don't.
This is one big reason I prefer to buy my yarn in person rather than via the internet - internet purchases often look far prettier on the monitor than in real life and colours are deceptive. (I do purchase yarn online, but it is usually something I've seen and touched first.)
