• Are you planning on producing merchandise? Tshirts? Stickers? other products? I need to know those details for technical purposes.
• Is it for personal or commercial use?

If it's for commercial use:

• Tell me more about your company and mission.
• Are there any specific guidelines or brandchart i should follow?

• When do you need the illustration completed? (Note that rushed projects will have extra fees)

• You have an idea in mind? Please share it :) The clearer it is the faster it will be.
• What is your message? Can you provide me a list of inspiration quotes. It could also be something you want to write on the illustration.
• Gather some illustrations you like to help me understand the mood of your project.

Here are some detailled questions i'll ask depending on merch:

Tshirt/ Apparels

• Do you already have a supplier?
• What color and model of shirt will you use? (This info will help me focus right away on the good palette for my illustration.)
• How many colors you want in the illustration? (If you screenprint your tshirt, the amount of colors matters cause the more you add the more it cost).
• Any specific colors you want to have in the design?
• How many illustrated elements do you need? (For exemple is it one big illustration in front /or/ 1 small illustration on the chest + 1 big illustration in the back /or/ Illustrations on the arms /etc.)

Stickers

• Do you already have a supplier?
• What is the final size of your sticker?
• Is there a special finish on the sticker?

Other Products (bottles / cups / van wraps, etc.) 

• Do you already have a supplier?
• Do they provide guidelines or templates
