So I love recolouring my clothing to make it more unique. But. The problem is that I use the basic paint on this computer. I wanted to know if theres any specific websites with cool fabrics, textures, or something. Like realistic fabrics to put on the outfits. I hope you get my point. Thank you

There are lots of websites with fabrics and textures out there (there's even a thread here on this site), but recolouring clothing won't be easy with a basic paint program. Ideally, you need something like Photoshop (which is expensive)... but you could also try the GIMP (which is free). You need something that's capable of handling layers, and both of those programs are.
