In the last two years I've had to buy new numbers and backgrounds four times. New bike, class changes etc. It costs me about $65.00 each time buying the preprinted numbers from DeCal works. I really like their stuff and it looks great and is durable. Now that I've got to change my numbers again I'm wondering if there is a less expensive way of doing this. Things are tight lately and I want to save some money. Does anyone just paint their own backgrounds and stick on numbers themselves?What is the best way to "do it yourself" and save some money?
