I have made quite a few different custom signs over the years, both in steel and in wood.
If a customer is looking to get a custom sign its important to know that I can’t just make a sign from a picture. For metal signs I can make a drawing from a silhouette kind of picture, but for a custom wooden sign I can’t go too detailed.
To make a drawing is very time consuming and I like to get as much information from the customer as possible. For example some people ask me if I can do the writing in a “bold hand writing font” but there are thousands of fonts so I would like to know the name. This saves me lots of work and time.
It also helps if the customer can give me a rough sketch (no it doesn’t have to be pretty). This will give me an idea of what you are looking for.
