Just spoke to my local spot today again on the yarns. Supposedly they got 1 of each size at each store. They're usually pretty good with giving me info, but sometimes they exaggerate to hype it up a little.
Online it could be hit or miss, but I think a decent amount of people will think its a cool idea, but how many they produced is what will make it a crap shoot. How much usable material did they actually have left over? Production dates on my yarn is 3/13/14 - 6/13/14. I don't have my fogs here to look at the GR production dates, but in 3 month I bet they could produce a lot of these.
The other issue is how many returns will there be from people hoping for a matching pair and getting one like my mismatched. Its a love or hate thing with that, and a lot of people could be sending them back if it happens to them
