Experimenting...

...how to use PicMonkey for editing and adding a texture.

EDIT: PicMonkey editing done

1) Textures
- Your own (opened from computer), Hardlight, Saturation 125%, Fade 30%
- I used this: www.ipernity.com/doc/serola/34487797

2) Effects
- Dark edges, Size 30, Intensity 40%

3) Text (for signature)
- Add text, Arial 12 white transparency adjusted

Finally just save on the image at Ipernity.
