* "Double Flemish" is a weaving technique, not a specific product. It's used to make a wide variety of things, each with its own cost based on materials, size, complexity, and the maker's skill and time.
* Materials vary. A double Flemish rug made from high-quality wool will be more expensive than one made from synthetic fibers. Similarly, a double Flemish tapestry using silk threads will cost more than one using cotton.
* Size and complexity matter. A small double Flemish wall hanging will be less expensive than a large, intricately woven rug.
* Maker's skill and location. Experienced weavers charge more for their time and expertise. The cost of labor can also vary significantly depending on the location.
To get an idea of the cost of a double Flemish item, you need to specify:
* What is being made? (e.g., rug, tapestry, wall hanging, etc.)
* What size is it?
* What materials will be used?
* Where will it be made?
Once you have that information, you can start researching prices from different makers. You can also find examples of double Flemish work online to get a general idea of costs.
