Copied from another board I posted on about bricks & mortar shops
North West FranceIn my short time here, I have located three.
Laval: Tissus du Centre, Route de Fougères, 53000 Laval. It's in an industrial unit on the industrial/retail park where Darty is located (at the Peugeot end).
Rennes: Tissus Myrtille, 173 Rue de Lorient, 35132 Vezin-le-Coquet
Le Mans: Tissus Myrtille, 92 Rue du Moulin aux Moines, 72650 La Chapelle-Saint-Aubin
Addendum.. There is another. Toiles de Mayenne, Le Bourg, Fontaine Daniel, 53100 Saint-Georges-Buttavent. I have not visited inside yet, so can't report accurately as to how good it is. My current understanding is that it has wonderful fabrics for household items and that it is expensive. One day will check it out.
Of the first three I mentioned, I love them all. Each has a great range of fabrics for just about any purpose from quilting, dressmaking, upholstery, crafting.. anything, really. They also have a great range of yarns and a myriad of haberdashery items. My nearest and dearest is very, very glad the shops are not closer to where we live...
