I stumbled on Barbara's site - stitchingupparis.sfr.fr - quite by accident doing research for my fall Paris trip. I had already been to the fabric district around Sacre Coeur, and so wanted to expand my horizons, and wow, did she ever!
She escorted me on two 1/2-day outings -- the first to various fabric, trim and vintage shops, and the second to the Vanves and Saint Ouen Flea Markets. We went to neighborhoods that most tourists probably don't see -- she custom-made the tours according to my interests, and I couldn't have been happier. Oh almost forgot we went to Deyrolle too, as a must see of course.
It was great to have an English speaker communicate with shopkeepers in French , and she gave me a map listing the places we visited, for future reference. She is a long-time quilter, needleworker and sewer, so we had much to discuss -- can't wait to return for more tours!
