I wasn't sure if I should put this in "Tips and Tricks", but it isn't really comic related.

Anyone here is experienced in painting on clothes? I'd like to maybe paint something on my leather jacket, and probably on a couple t-shirts and shirts as well. But I have no ideas what paints to use, what's the most resistant to water, etc.

If anyone has tips or suggestions on the materials to use or the techniques used, feel free to share them. Same thing if you want to show images of what you've done.

I've painted some stuff on my leather jacket, I used a white Testors paint marker. Naturally they were really simple monochrome designs but they added some character. The Testors marker is pretty waterproof and also pretty hard-wearing, though you'll notice the fumes if you use it so if you do go with that use it in a well-ventilated area.
If you're thinking something more elaborate ask Pit-face about it-- she also painted her jacket with some pretty elaborate designs, I think she used acrylic paints but that might be wrong.
As far as other clothes, I've known people that use stencils and spraypaint which seems to work well for simple designs for more complex designs screen-printing would be a better bet, I've also known some people to use block-printing, (presumably linocut with screen-printing fabric ink,) on shirts as well.
Hopefully that'll get you going.

I've painted simple stuff on fabric before (and more complex stuff on canvas of course).
I used fabric paints that are specifically made for that sort of thing. You had to heat the fabric a bit afterwards to properly fix it, but it worked pretty well.
With leather, I dunno. As Patrick says, Pit has done it.

Different paints go differently on it though. Acrylics and stuff like that will mostly form some sort of a bonding over the surface, whereas that stuff that Patrick mentioned will stain it deeper into the skin and probably last longer during wear.

Thanks for the advices. I'm not sure where I can find Testors markers, nor special fabric paints, but I'll try looking in more artshops than the one I always go. I'll probably go with something simple to start because I don't have any piece I can practice on first.

I found my Testors in a hobby shop, the kind that sell plastic models. A good thing to ask when visiting an art store is if they stock screenprinting supplies, if they do they probably have inks/paints suitable for fabric.

For cloth, acrylics would be fine, even the cheap craft acrylics sold in bottles. I've sprayed these with air brush on T-Shirts and they do fine and don't need to be set with heat.

On leather, most use acrylics as well. But, you have to prepare the leather with 'leather bleach' or similar deglazer to clean and knock off the surface a bit. After that, it's just a matter of painting in thin layers (keeping the leather a bit damp with water helps). You want to let each coat dry, and then flex the area a bit to let it follow natural cracks. the next layer of paint can fill those in. Then after you've finished, a thin coat of acrylic varnish should be applied.

Be careful with cheaper acrylic paints- they're cheap for a reason.
The pigments tend to be very photosensitive and will fade a LOT over time, depending on the colour. I think the blues tended to be particularly weak (from memory).

And when I say "over time" I mean in a pretty short time, depending on how much direct sunlight the paint gets.
