ROVING BARROWS & CARTS & WAGONS & BASKETS
One thing to bear in mind if using a wagon or barrow or cart, is height. Be sure the framework is above the average head height so you can be seen in a crowd. Flags and pennants help add height as well.
Carry a wooden stool for your comfort.
If strolling and selling your wares from a basket, be sure to use a loud voice when Hawking to gain notice.
