And I find it's grown a bit over the past 12 months - I've added another half a shelf (give or take a bit). I'm not sure if that's because there are a lot more knitting books (that I want to buy) being released, or if it's because I discovered Kinokuniya has a great crafting books section, or if it's because (as my mum would say) my eyes are bigger than my belly.
I suspect it's a combination of each of those reasons.
Now don't ask me how many of these books I've knitted something from - but I have queued a lot of patterns (and I may have a lot of yarn allocated for these projects too, but shhh don't tell)!!
