Oh dear, 20 whole minutes away? however will you manage?
Sorry for giggling at you, but I live in the country and EVERYTHING is at least 30 minutes away. 20 minutes actually seems like a lot closer to me.
I have two LYSs near me, one to the north and one to the south. The one to the north is smaller, I've never bought anything there but the woman is super nice and I love hanging out with her and showing her the stuff I'm knitting and helping her with her website.
The one to the south is on my route to/from work, but the one time I went in there to buy a specific skein of yarn and see how I liked it, the lady was NOT very friendly and ignored me the whole time. She seemed really put upon that I walked in half an hour before closing time.
Also near me is WEBS, and I walked in there on my birthday to buy some new needles and it was 15 minutes before closing and they were STILL super nice. The girl even remembered me and asked my husband if he was with me, it was cute.
I'm planning on going to the north LYS and buying the sock yarn for Sock Wars soon (yeah, it's coming) just because I feel so bad about going in there all the time when I don't have a yarn budget!
