I find the staff to be sort of distant, but the selection more than makes up for it. I'm not at the store to chat, I'm there because they always have in stock every colorway of Lamb's Priode, Cascade 220 & Superwash, Misti Alpaca, Encore, and much more. The selection really is mind-blowing.
Large and diverse selection of yarns--it might not look like very much at first, but the entire upstairs is all yarn and books, the largest and most well-organized book selection I've seen in a yarn shop. I was very impressed, and I was even able to make it to their annual New Year's Day sale, where all yarn is at least 20% off.
I stopped into Stix while in Bozeman on a busines trip. At first I walked right past it becuase it's downstairs. Look carefully! It didn't look that large going down the stiars, but after I wlaked in, I saw a whole other room in the back, plus a huge room around the corner. This place has everything! What an amazing yarn selection. The prices are reasonable and the staff is super friendly and helpful. I actually came back the next day to buy some more yarn. I loved this store.
