Or... you can come outside, take a quick left turn, hit the book up to PoK and either pick one up there or take a stone down to Qeynos or Freeport. There must be a Gazillion of the things in those two towns!
After all, it's nice to get out and see a bit of countryside now and again. And, since all three of these books are located in newbie zones, you'll be perfectly safe traveling to and from home and PoK is a neutral zone so no worries there either. Have a nice trip!
One more thing... if you think you're EVER going to do any real tayloring (as opposed to just the thread out of silks thing), go ahead and invest in the large kit now and forget about getting the small one at all.
Just my 2CP...
