Bed sheets, general house and baby stuff shopping in lyon?

Hi everyone! Hoping for advices on shopping places at lyon on good quality cotton bedsheets,  bathroom towels, kitchen equipment and like.  I want cotton but all what I can see online is quite expensive and we have just moved here and as probably you know we have to buy everything as rented accommodation is empty. Also im 6 months pregnant and not able to take loooong walks around just to get disappointed at finding another store that I cant afford. So please tell me....where I can go?
Also..baby prefold washable diapers, made of cotton and bamboo and cover fpr it if you would know? ?

Thanks
