How are iPhone Case desings made?

There's this girl where she makes her on iphone cases, I draw alot and I want to know how do you print your design on the iphone case, ipad case, etc. I hate not having my own money so I want to earn my own money, I'm always sick so I can't get a job. Is their some sort of printer that prints on plastic? Or what do I need to make my own handmade cases?

If you got a picture of something you want to put on an iphone case, walmart can do it for you.

I'm sure she buys the cases and prints the designs onto a material that has a sticky back to it. The equipment to print directly to the case would be very expensive.

You would need some money to buy the cases, and the self adhesive material.

You might contact her directly and ask her some questions about how she does it. Just say you doing it as a school project or something. But she might not tell you here secrets. She might also not be doing very well. Sales might be few and far between.

My daughter sells hand made jewelry at craft shows and does well because most of her stuff is less than $15 when lots of other people sell for over $25. $20 or more is a lot to pay for a cell case that you can't hold in your hand.

My 2 cents.

It is a good idea, if you make your own iPad cases and sell them for making money. Generally a case that is made by a designer is quite expensive than an general case. At first, you need to buy some blank cases and then you can make a design on it. Some Youtube videos can help you. I saw suchlike videos.So, please search in Youtube to get some relevant tutorials.
