Taquilians were considered the best weavers in the Inca Empire. It's common seeing men and women weaving in the streets while they walk.
There is a two floor handcraft market in the main square where you can buy from tipical perubian hats to skits, most of them made of alpaca wool. The price is more expensive than other places, but the quality is also supposed to be better.
Who could resist?? We bought a wonderful wind - chime...it's made of reeds and has the mos intricate work . Little boats with people in them hanging from a reed dome. It's special and when I look at it I remember this fascinating place. ( I think it was all of $2.00)
In the Uros islands you will find many souvenirs stalls. Is usually stuff they make there, like ceramics, small totora items like boats, huts... They are really cheap, about 1-2 USD, and you can even bargain. Is a good chance to buy those identical souvenirs for your 12 mates at the office or so. If you buy many items you can get discounts. And think this is one of their only ways of surviving...
