The pack includes a set of 3 grunge cloth textures. These can be used for whatever you consider fit.
You are not allowed to redistribute or sell these resources as your own because they belongs to me. I give everyone full permission to use them in both commercial and non-profit work, without asking anything in return.
It would be nice if I could see how and where you used them and I encourage you to leave me a link with your finished work and/or link back to my website from the place you posted the original work, however, this is not mandatory, it is just appreciated and I would consider it a sign of common courtesy.
