We will be using the "Old Truck" transfer with all kinds of add on transfers. For the cost of $40 the surface will be a framed 9x12 chalkboard. For an additional $10 you can work on a 12x18 framed chalkboard which will allow you more room for additional designs. This transfer has layering and time will need to be allowed for layers to dry real well. I will have my hair dryer available to helo with the drying process.
