designs for clothing

[Tgigli]

Hi all, im new here. I have some experience with Photoshop but i have never designed something for clothing. Now i want to design some stuff for t-shirts, sweaters, caps etc. I wanted to know are there any special things i should think off?
And what are the best settings to design on, like resolution and stuff.

Ps. im sorry if my english is a bit bad, i'm trying ;)

Thanks in advance

Welcome to PSG, Tgigli.

Do your work images at 150ppi.

If these are for a client, ask them for images of their products.

If embroidery is concerned use the least number of colors in your design.
