Madaba mosaics
Workshops in Madaba sell mosaics made on site; ask to see the workshop before you buy.
Ask who made a piece and where. Check materials and shipping. Bargain politely only where invited; respect fixed prices in boutiques and artisan shops. Bargaining is normal in the downtown souqs and at Petra’s stalls; malls keep fixed prices.
