Christmas Clipart cards: a person can use Clipart and a printer to create their own Christmas cards
These sites often have other designs besides Christmas pictures as well. You can find websites that have 4th of July clipart and Halloween clipart and even Easter and St. Patrick's day clipart.

Do have a professional cartoonist/graphic designer develop it for you. There are many fine nuances that go into a well-designed cartoon brand mascot. What looks good on the sketchpad may not look good when it's reduced down to fit on a business card. A cartoon brand mascot may need to look good on a computer screen, embroidered on a shirt, etched on a pen, printed on a business card or blown up on a billboard. A good designer knows how to use the proper line weights; colors and shading that reproduce and hold their integrity over a wide array of applications.
