I would like to buy some local handcrafts as gifts to my friends and relatives .  There are many stores selling handcrafts in Paris . Our store is wellknown for vase , table wear and jewelry boxes . You can take your time and choose whatever you like .  Well , the tapestry is delicate and beautiful .  You have made an excellent choice , it is our newcomer . The tapestry is on hot sell with the design and quality . The design on it is traditional Paris architecture .  How much is it ?  100 frances .  Mmm , it is reasonable . Look at this set of table wear , it is so beautiful !  We have a piece of table clothing to go with it . It is a brocade one with pretty stars .  This silver vase is a good ornament for the living room .  You are right .  I will take the tapestry , the set of table wear and the vase .  OK . Do you like these candles ? They are on sale now .  All right . I will take one .
