Plastic Cabinet Knobs

Plastic Cabinet Knobs
Does anyone know where to buy a design template for Kitchen Cabinet Knobs?

I am looking for a plastic template with holes to show where to drill holes for cabinet knobs. DIYnetwork.com says they are available in stores for home improvements, but I can not find them. Has anyone seen or used them? If anyone has a link online, we would be very grateful.

I bought one last year of any of Lowe's or Home Depot. Only a few dollars if I remember correctly. Due to the shape of the edge of my cabinet doors, it was very difficult to get aligned properly. If I had to do it again, I probably do mine with a few pieces of scrap wood.
