: How can I mockup a custom stripe fabric on a t shirt I am starting a clothing brand and I want to create mockups of stripe designs that I do in illustrator so I can have a realistic look

@Margaret771

If the canvas patterns are only as computer files, you can well present them on a shirt with illustrations. Real canvas would have rich details which unfortunately are unknown. So do not guess them. Take proper photos after you have something physical. After that you can also make some fake photos as mockups when you know how your ideas get materialized (=how your patterns get bended and folded along the canvas)

Here's an example:



A coarse shirt was drawed with the pen in Illustrator. Only a half was made because L-R symmetry was assumed. The shirt was thought to be without any bumps and foldings. I do not know much about textiles, so this is based on guessing and some low quality T-shirt photos that I have seen in the web.

The different canvas pieces were colored with the live paint tool to get closed shapes. The line drawing was moved aside.

A simple stripe pattern was generated as a bunch of rectangles. The white is not full 100%, but about 90% to leave some room for highlights and keeping it a little different than white background.

Two copies of the half shirt, the other flipped, were aligned. Some pieces got solid grey fill color and 3 pieces got the drawed stripe shape (rotate and clip as needed, clip is made with Object > Path > Divide Objects Below).

Clipping masks can be useful and also having the canvas pattern as fill swatch. They are not used here.

The final illustration can have some 3D-like forms. The colored shirt was warped and shaded to look out a little more random and to have some bumps and bends.



This phase was done experimentally in Serif Affinity Photo which seems to have an excellent warp tool. The shading is some blurred black and white strokes in a new layer which has reduced opacity and blending mode = Hard light. The exessive blur was deleted by making a selection with the warped shirt. Blurred black and white work also in Illustrator, but there's more handy tool for this: The gradient mesh.

This can seem complex, but the deformations are arbitary. I wasn't forced to slavishly copy anything existing. That's why the warping and shading took only few minutes. Foldings and wrinkles are a lightyear more difficult, so they are skipped.

All presented can be done in Illustrator, which has a big advantage: You can edit or change shapes and patterns behind envelope distortion mesh. That makes possible a template that needs only to change the canvas pattern and colors to get a new shirt. Geometric forms including bends and bumps stay, if wanted.

Shadings and color and light adjustments are easy to reuse in Photoshop and several others, but I have not found a practical way to reuse envelope distortion in other software than Illustrator. But, as written, simple deformations can be done from scratch in a couple of minutes.

For cloth designer's there exists 3D modelling software which can create realistic foldings and wrinkles. Watch this

You need to look into Photoshop "Transparency Masks".

Here is one way to do it, out of many:


Take an image of a t-shirt.

Select the t-shirt. Here I've just used Quick Selection Tool, but you could use any method you like. Use Refine Edge to fine tune the selection if you want.

Create a new Group, click the Mask button to convert the active selection of the t-shirt to a mask on the group. Set the Blend Mode of the group to "Multiply".

Now, everything you put inside the group is confined to the shape of the t-shirt. The "Multiply" blend mode makes the colors of the group tint the underlying t-shirt instead of covering it.



The mask is a grayscale image, shown as a thumbnail to the right of the group symbol/layer thumbnail. The darker the mask gets, the more transparent the content of the layer it is applied to gets. And the whiter it gets, the more opaque.

The mask can be clicked and then edited. If you ALT-CLICK the mask, you enter "mask mode" where the mask is displayed in grayscale. Click the layer thumbnail to return to "normal mode".

Always pay attention to the smoothness/raggedness of the contours in your mask, since they define how well your layer blends together with the rest of the image.
