Does  any one know about a crafts store (something like Michael's) somewhere close to here? 

What is it you are looking for?  Leroy Merlin and Bricomart have some craft stuff.  I've been to both, I can tell you if they have what you need.

What and where is Bricomart?  I am looking for yarn and material to reupholster a couch... I have been to Ikea's material section and was looking for some more of a selection.  

Bricomart is right next to Campania Mall.  They have a selection of fabric.  Leroy Merlin also has fabric.  not sure about yarn.

I have also seen fabric, some upholstery grade, at the markets, bigger ones, such as Vomero. I do some upholstery and have been keeping an eye out for fabric as well and the Vomero market had some that I would consider for upholstery. I saw a place in Aversa that has the foam and batting for upholstery if you need that. I did not have my GPS on me, but I wrote down the name of the street, Via Giovanni Boccacio, in Aversa.
