Chalk and Cheese have a retail outlet at 22 Mills Street Strand. Open Monday to Friday 09:30 – 17:00 and on Saturdays from 10;00 to 13:00. They stock a number of different stencils. All sizes. They will also arrange for custom made stencils to be made for you. Ask for a cup of coffee. They also made a super cup of freshly gound! But you have to ask, it’s not a coffee shop.
